A microwave transmits waves at just the right frequency to make water molecules vibrate, thus heating anything in range that has water molecules. This can be proven by placing an empty ceramic plate in the microwave, and turning the microwave on; now put something such as a carrot or a piece of chicken on the plate, and heat it again. The plate on its own will have stayed cool, but with the food on it, the food has been heated, and some of the heat has transferred to the plate. One of the problems with microwaves is that they 'leak' microwaves, especially at the front area, which often has a viewing window. The effect of microwaves on human tissue has been thought to cause cancer, but it has not been proven. The effect of microwaves on the brain makes it heat up my approx. 1 degree Celsius - this speeds up the neurons in your brain; this could make a person slightly 'cleverer', however, it could also cause damage.
What else can I help you with?
Will a microwave work in space?
No, a microwave oven would not work in space because microwaves rely on the presence of air molecules to transmit heat to the food. In the vacuum of space, there are no air molecules to heat up the food, so the microwave would not function properly.
How does a microwave oven work to heat food quickly and efficiently?
A microwave oven heats food quickly and efficiently by using microwave radiation to excite water molecules in the food, causing them to vibrate and generate heat. This heat is then transferred to the rest of the food, cooking it evenly and rapidly.
What forces are in a microwave?
In a microwave, the main force at work is electromagnetic radiation. This radiation causes water molecules in food to vibrate rapidly, generating heat through friction. The rotating plate inside the microwave helps to evenly distribute the heat.
What is a microwave kiln and how does it work?
A microwave kiln is a small kiln that uses a microwave oven to heat and melt materials like glass or metal. It works by using the microwave's electromagnetic radiation to heat the materials quickly and evenly, allowing them to reach high temperatures for crafting or melting purposes.
How does a floating microwave work in space?
A floating microwave in space works by using solar panels to generate electricity, which powers the microwave to heat up food or liquids. The lack of gravity in space allows the microwave to float and heat up the contents evenly without the need for a rotating turntable.
What method of heat transfer is used when cooking a baked potato in the microwave?
The main method of heat transfer used when cooking a baked potato in the microwave is radiation. Microwave ovens work by emitting electromagnetic waves that cause water molecules in the food to vibrate, generating heat and cooking the potato from the inside out.
How do microwave ovens work to heat food quickly and efficiently?
Microwave ovens work by emitting electromagnetic waves that cause water molecules in food to vibrate, generating heat. This process heats the food quickly and efficiently, making it a convenient cooking method.
Does a microwave transfer heat by radiation?
Yes, a microwave transfers heat through radiation. Microwave ovens use electromagnetic radiation in the microwave frequency range to heat food by causing water molecules in the food to vibrate and generate heat.
Why does a plate not heat when in the microwave?
Yes if it is microwave proof
Can you heat a plate in a microwave?
Yes if it is microwave proof
Is there any radioactive material in microwave ovens?
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
Why do empty dishes do not heat up in a microwave?
Empty dishes do not heat up in a microwave because there is nothing for the microwave energy to interact with and convert into heat. The microwaves require water molecules or other substances to absorb them and generate heat, which is why only food or liquids heat up in the microwave.
