How Microwave oven works | Characteristics

The microwave oven is among the most important inventions of the 20th century. A microwave oven is a staple in millions of American households. Consider how often you use your microwave every day. There are many people who are still finding the difference between Microwave and oven. Here are a few tips which help you understand the difference easily.

You have to be at work by 2:30 so that you can make breakfast at home. On your way to work, you stop at the gas station to top up your car. Grab a frozen breakfast burrito at the quickie-mart, and heat it up in the microwave. Lunch will be finished later in the day. By 3:00 p.m., you’re hungry so grab some microwaveable popcorn at the vending machines and pop it in the microwave. It’s too late for grilling after a long day of work so make last night’s lasagna in your microwave. Some of the best OTG microwave ovens allow you to set the temperature without hassles.

It is easy to see how microwave ovens can quickly cook food. Microwave ovens do not heat food and are therefore very efficient at using electricity. We will be discussing the secrets of microwave cooking and the “meals within one minute” phenomenon.

Important Characteristics of Microwave ovens

Microwave ovens heat food by using microwaves. Microwaves are radio waves. Radio waves are the most commonly used frequency for microwave ovens. It is 2.55 gigahertz, or approximately 2,500 megahertz. This radio wave has an interesting property. They can be easily absorbed by fats and sugars as well as water. When they are absorbed, they become heat. This is an interesting property of microwaves. They are not easily absorbed by ceramics, glass, and plastics. Microwave ovens reflect metal so metal pans will not work in them.

You often hear that microwave ovens can cook food from within. What does this actually mean? This explanation will help explain microwave cooking.

Baking with oven

Let’s say you want to bake a cake in a traditional oven. Normal baking temperatures are 350°F. Let’s say, however, that you accidentally heat your oven to 600 degrees. This will cause the outside of the cake to be burnt before it warms up inside. Conduction is the process by which heat moves from the outside to the middle of food in a conventional oven. Learn more about conduction at How a Thermos Work. Also, the food has hot, dry air that evaporates moisture. Crispy brown can occur on the outside of food (e.g. Bread crusts can form on the outside of food, while the inside remains moist.

Radio waves are used to penetrate food and excite water molecules evenly in the microwave oven. Conduction doesn’t allow heat to flow towards the interior. Heat is everywhere because all molecules are excited together. There are limits. Radio waves can penetrate thick food pieces unevenly (they don’t reach the middle) and there is interference from wave waves. You get the idea. The whole heating process will change if you “excite electrons” rather than “conducting heat.”

Easy to set temperature

It is impossible to make crust in a microwave oven because the oven’s temperature is room temperature. A small foil and cardboard sleeve is often included with microwaveable pastries. This sleeve helps to place food in the microwave. The microwave heat can cause the sleeves to get very hot. Thanks to the heat from the outside, the crust becomes crisp.

At least 31 killed as rain triggers mayhem in Mumbai

At least 31 persons, including eight minors, lost their lives in Mumbai as incessant rain from Saturday night and throughout Sunday triggered a landslip, house collapse and electrocution.

The Regional Meteorological Centre of Mumbai has predicted heavy to very heavy rainfall at few places, with extremely heavy rainfall at isolated places.

The Brihanmumbai Municipal Corporation said more than 200 mm of rainfall was recorded between 11 p.m. on Saturday and 4 a.m. on Sunday. A BMC centre at Dahisar recorded the highest 226.82 mm of rainfall, followed by Chembur with 218.45 mm.

Nineteen people were killed and five injured at Vashi Naka in Chembur after a retaining wall collapsed on four or five huts due to the force of water and mud around 1 a.m.

A landslip at Panchasheel chawl in Vikroli on six houses around 3 a.m. resulted in the death of 10 people while one person was injured.

Soham Thorat, 16, died after a wall of his house at Kombagalli in Bhandup area collapsed, while one person was electrocuted at a shop in Andheri.

Five battalions of the National Disaster Response Force were deployed in Chembur and Vikroli to speed up rescue efforts. The search was on for two more missing individuals at the time of writing this report.

“I visited the 3 locations of landslips … Relief work is going on and all necessary financial and medical assistance is being provided by the Govt of Maharashtra and BMC,” Environment Minister Aaditya Thackeray tweeted.

President Ram Nath Kovind, Prime Minister Narendra Modi and Chief Minister Uddhav Thackeray expressed condolences at the loss of lives in the Chembur, Vikhroli incidents. “The next of kin of those who lost their lives in the mishap will receive ₹5 lakh each from the State and those injured will be provided with free medical treatment,” said Mr Thackeray.

In view of the IMD forecast of heavy rains on Sunday, CM directed all agencies to stay on high alert and launch immediate rescue and relief operations in case of any mishaps. “If the water levels in the Mithi or other major nullahs rise above the danger level, those staying in nearby areas must be relocated to safer locations immediately,” he said.

Rains have also posed water shortage problems in front of the city as due to the inundation of rain water in the Bhandup Water Purification Complex.The Filtration and Pumping plants at the complex had to be shut down as a precautionary measure.

“Due to this, water supply in most of the parts of Mumbai has been disrupted today (Sunday). Efforts to restore Mumbai’s water supply are being made on war footing. We urge the citizens of Mumbai to boil potable water before consuming it, once the water supply is restored,” said the civic body press statement.

Heavy rains also resulted in water logging at 31 locations across Mumbai and 20 traffic diversions had to be announced. Several suburban local train services were also hit due water logging on tracks.

The rains have also brought good news to Mumbai as days after overflowing of Tulsi lake, one of water bodies which supply water to Mumbai, Vihar lake too overflowed at 9 AM on Sunday.

The IMD has predicted heavy to very heavy rains in the next 48 hours. It also expressed the possibility of occassional gutsy winds reaching 45-55 kmph gusting to 65 kmph. “In view of the likely formation of a low-pressure area over Northwest Bay of Bengal & neighbourhood around July 23 and associated strengthening of westerlies, parts of Konkan Goa and adjoining ghat areas of Madhya Maharashtra is very likely to experience an active rainfall spell during next 5-6 days with heavy to very heavy rainfall at a few places and extremely heavy rainfall at isolated places,” the release said.

Chief Minister Uddhav Thackeray on Sunday evening held a meeting with senior officials in the state to take stock of the situation arose due to incessant rains.

Monsoon Arrives In Delhi After Long Delay; Massive Jams After Heavy Rain

Delhi Monsoon: The India Meteorological Department (IMD) had predicted moderate rain over Delhi this morning.

New Delhi: The long-delayed monsoon finally arrived in Delhi today as heavy rain and thunderstorms hit the national capital this morning leading to massive traffic jams. The city’s adjoining areas like Gurgaon and Faridabad have also received rainfall.
The India Meteorological Department (IMD) had predicted moderate rain over Delhi this morning.

The southwest monsoon’s arrival today after a string of IMD’s incorrect predictions is the most delayed in Delhi in 15 years. The weather office faced a lot of criticism and called the failure in prediction “rare and uncommon”. The IMD’s last prediction was monsoon’s arrival last Saturday as Delhi and adjoining areas reeled under intense heat for weeks.

The Monsoon had reached almost all parts of the country but had stayed away from Delhi, Haryana, parts of west Uttar Pradesh and west Rajasthan. The weather forecasting agency had predicted that monsoon is expected to cover these parts by June — a little less than a month back but that did not happen.

K Jenamani, a senior scientist at IMD has said they will study why the arrival of monsoon was delayed in Delhi despite favourable conditions.

GlobalData report estimates India’s coal production to rise by 6.4%; Hindalco, Adani Group in Chhattisgarh to support sector

Total coal output in India is expected to increase by 6.4%. Private companies such as Hindalco, Vedanta, Adani Group Chhattisgarh and other coal-bearing states are expected to be major players.

According to the latest report by the UK-based analytics firm GlobalData, India’s coal production is estimated to surge by 6.4 per cent i.e., from 777Mt in 2020 to 827.8Mt in 2021. The major factor for the rise in total output is the entry of more private players in the sector.
Private players such as Hindalco, Vedanta, Adani Group Chhattisgarh and more have been managing coal blocks across Chhattisgarh and other coal-bearing states. This will play a crucial role in realising the government’s vision for the sector.

The UK-based analytics firm expects India’s coal production to rise at a compound annual growth rate (CAGR) of 9% in order to reach 1.2Bnt by 2025. The government’s target, on the other hand, stands at around 1Bnt. However, Vinneth Bajaj, a mining analyst at GlobalData said that the ongoing pandemic might pose some challenges to this estimation.
The sudden increase in new covid-19 cases since March 2021, has hampered the coal operations in India. Despite this, there was an uptick in coal offtake in the month of April this year, which strongly indicates a revival in demand in the coming months.

The sector is largely influenced by the coal-rich states like Chhattisgarh. The latter has over 16 per cent of the total coal deposits of India. The state also ranks 2nd in the total coal production by contributing more than 18 per cent to the overall production of the country.

With numerous coal mines containing huge reserves in different districts, the state is highly preferred by the miners. To simplify the auction process and attract major investors, the government had also amended the Coal Mines (Special Provisions) Act, 2015 last year. Over the years, Chhattisgarh has seen the involvement of several private and public entities across the mines, which largely drive the economy.

To operate coal mines with the latest technology and boost competition, Adani Group mining Chhattisgarh signed a pact with Maharashtra State Power Generation Co Ltd for the development of the Gare Palma Sector II coal mine. The mine’s peak rated capacity and total mineable reserve stand at 23.6 million tonnes per annum and 553.177 MT, respectively. The project in Chhattisgarh by Adani Group, which include minedevelopment and final mine closure, will run for 34 years.

In the same state, Adani Enterprises, the flagship company of the Adani Group, launched MDO operations at the Parsa East-Kente Basan mine that is owned by Rajasthan Rajya Vidyut Utpadan Nigam Ltd (RRVUNL). The estimated coal reserve in the block was 450 million tonnes. Post the coal supply by Adani Group in Chhattisgarh, Rajasthan might become power surplus.

Apart from this, mining giant Vedanta Ltd had bagged Chotia block in Chhattisgarh during the first phase of coal mine auctions. In the near term, the yearly output from the block is estimated to reach 1 million tonnes. On the other hand, Aditya Birla Group’s Hindalco Industries had also won the final bid for Gare Palma-IV/5 in Chhattisgarh with extractable reserves of 42.43 MT per annum.

Considering the richness of the state in terms of coal, Sarda Energy and Minerals placed the winning bid for Gare Palma IV/7 coal mine in Chhattisgarh. The mine has a total geological reserve of 234.205 million tonnes and the company quoted a major revenue share of 66.75 per cent during the first tranche of commercial coal mine auction in India.

India is increasingly unlocking the participation of private entities in coal mining. This will play a key role in improving the sector’s overall revenue and reducing dependency on imports. It will also fulfil the government’s objective to promote transparency, leverage technology, competitiveness and more. The government has also been laying a robust framework to enhance productivity and reduce environmental impact across the mining operations.

Recently, the government has also announced to offer 67 mines with a total resource of almost 36 bn during the 2nd tranche of coal mines auctions for commercial mining. It will be the biggest offer of coal mines in India.

Out on bail, gangster Kulbir Naruana shot dead by associate in Bathinda village

Naruana was facing more than 15 cases and was currently out on bail. The accused, identified as Mandeep Singh, alias Manna, (35), has been arrested. He was taken to hospital after he sustained injury in crossfire.

Kulbir Singh Naruana, a 39-year-old gangster, who had lately taken up social work, was Wednesday shot dead outside his home in Bathinda’s village Naruana allegedly by an associate with whom he had had a fallout over some issue.

Naruana was facing more than 15 cases and was currently out on bail. The accused, identified as Mandeep Singh, alias Manna, (35), has been arrested. He was taken to hospital after he sustained injury in crossfire.

According to the police, Manna had gone to meet to sort out some differences. Both had tea together and later Manna, called Naruana inside his SUV, where he shot him five times, killing him at the spot. Naruana’s friends tried to stop Manna from driving off. However, Manna ran over one Chamkaur Singh — another accomplice of Naruana — killing him on the spot. One Gurpreet Singh also sustained a bullet injury in the crossfire and is under treatment.

“Manna has been arrested and is in hospital. He has confessed to the crime. He killed Naruana in a spur of the moment, according to his statement. Investigation is on,” said Bhupinderjit Singh Virk, SSP Bathinda. Manna has been booked for murder.

Naruana had over 26 cases against him for murder, attempt to murder, as well as under the Arms Act. However, for the past 3-4 years, he had been trying to change his “public image”. Sources said he used to donate money for marriage of women from poor families and used to help the needy. He was even presented a robe of honour by former minister Bikramjit Singh Majithia in March 2014, when Congress leader Jeet Mohinder Singh Sidhu had joined the Shiromani Akali Dal (SAD). However, in July 2014, he was arrested with illegal weapons, and later released on bail. In January 2015, he was arrested again in a case of firing at a policeman when he was forcibly trying to take possession of a house.

In another incident, he had put red chilli powder in the eyes of policemen at Bathinda Civil Hospital in order to get a convict, Gurwinder Bindu, freed from police custody. “A few cases had been settled while still a number of cases are ongoing,” said a Bathinda police officer.

Manna too has over 18 cases pending against him, said the Bathinda SSP.

Naruana was attacked on a previous occasion as well. On June 21, when he was going towards Malaut, unknown persons had fired at him but he had escaped unhurt as his vehicle was bullet-proof, police said.

Meanwhile, a 15 minutes-long video of Manna has gone viral in which he mentions that Aziz Khan — a Congress member and vice-president of Nagar panchayat of Talwandi Sabo — had threatened him on Facebook because he had extended support to a person who was allegedly beaten up by Khan’s men. Manna had even challenged Khan and his supporters to talk to him straight, rather than writing on social media. He claimed that Khan had later deleted his comments.
