What kind of energy makes a microwave work?
Microwaves work by producing electromagnetic radiation in the microwave frequency range. This radiation generates heat by causing water, fat, and sugar molecules in food to vibrate quickly, creating friction and heating the food.
What kind of energy does a microwave oven use?
A microwave oven uses electricity to generate electromagnetic radiation in the microwave frequency range. This radiation is absorbed by water, fats, and sugars in food, causing them to vibrate and generate heat, which cooks the food.
What type of energy does a microwave produce?
A microwave produces electromagnetic energy in the form of microwaves. These microwaves agitate water molecules in food, causing them to vibrate and generate heat through friction, which cooks the food.
What unit of energy is a microwave oven measured in?
Energy - of whatever kind - is measured in Joules. Power (energy per time unit) is measured in Watts.
Which manufacter sells the most microwave ovens?
GE (General Elecric) sells the most microwave ovens. They sell approxamately 30% of all countertop ovens (the kind that is most common).
What kind of radiation are microwaves?
Microwaves are a form of non-ionizing radiation. They have lower energy than ionizing radiation such as X-rays and gamma rays, and are used in microwave ovens for cooking food by causing water and fat molecules to vibrate, generating heat.
Is a microwave oven a cube?
Most microwave ovens are a rectangular box of some kind, but there are a few that are shaped like cubes.
What kind of compound is microwave?
Microwave is applying microwave radiation to chemical reaction.
What kind of radiation is used by mobile phones?
Electromagnetic radiation, in the microwave portion of the radio spectrum.
Do the sunbeams absorbed by the earth get radiated as a different kind of radiation?
They mostly get radiated out as Infra-red (Heat) and microwave radiation

What kind of device is Presto PowerPop?
The Presto PowerPop is a popcorn maker, intended for the microwave for convenience. It fits in most microwave ovens and can be used with oil for a buttery taste or without oil for a healthier snack.
What kind of simple machine is oven?
A microwave oven, or a microwave, is a kitchen appliances that cooks or heats food by dielectric heating. This is accomplished by using microwave radiation to heat water and other polarized molecules within the food. This excitation is fairly uniform, leading to food being adequately heated throughout (except in thick objects), a feature not seen in any other heating technique.Basic microwave ovens heat food quickly and efficiently, but do not brown or bake food in the way conventional ovens do. This makes them unsuitable for cooking certain foods, or to achieve certain effects. Additional kinds of heat sources can be added to microwave packaging, or into combination microwave ovens, to add these additional effects.Microwaving food raises several safety issues, but also reduces certain risks, such as that of fire from high temperature heat sources.
What kind of energy makes a microwave work?
Microwaves work by producing electromagnetic radiation in the microwave frequency range. This radiation generates heat by causing water, fat, and sugar molecules in food to vibrate quickly, creating friction and heating the food.
How does a microwave work?
A microwave oven heats food in a process called dielectric heating. The molecules in the food, primarily water molecules, are polar molecules - meaning they have both a positive and a negative pole due to the distribution of positive and negative charges on the atoms. When they are subjected to microwaves, the molecules rotate as to align themselves with the electromagnetic field, much like a compass aligning itself with the magnetic field of the Earth. Microwave ovens alternate the electromagnetic field to reverse the polarity, causing the molecules to then rotate the other way. Using the compass analogy, imagine taking a magnet and doing circles around the compass; the needle goes crazy. This excited rotation of (mostly) water molecules generates molecular friction with other surrounding excited molecules, generating heat.A common misconception is that the molecules have resonance with the particular frequency used by a microwave oven; ovens that use different frequencies can cook just as efficiently. Another misconception regards the safety of microwave ovens and their radiation. The radiation used in a microwave oven is in the form of radio waves; this is non-ionizing radiation, meaning it is not the same kind of radiation that can cause cancer; that kind of radiation is called ionizing radiation - sunlight and nuclear radiation are examples. Therefore, a microwave oven's radiation cannot cause cancer or other ionizing effects. It's also commonly believed that standing too close to a microwave oven can be harmful, but this is not true. A microwave oven acts like a Faraday cage; the holes in the metal grill that's visible through the oven door are essentially invisible to the radio waves, thanks to their wavelength, so most of the energy is reflected back into the oven. Other sources of microwave radiation, such as cell phones, cannot heat objects like a microwave for two reasons: The relative power of the transmission, and the fact that a microwave oven concentrates nearly all of the energy into the food, whereas a cell phone's transmissions dissipate in all directions, leaving the tiniest fractions of that energy to be absorbed by the body.It heats up and thaws the food that you have placed in the microwave

The Sharp R1870 with 850 watts cooks very fast.
