a machine that transforms heat into machanical energy, or work
microwave
The use of a machine to move air. In medical terms, a machine to aid a person in breathing by moving air into and out of their lungs.
The mechanical advantage.
All people use mechanical energy.
No, this microwave is not energy star approved. In fact, Energy Star does not currently approve/label ANY microwave ovens. However, most microwave ovens of the same size/wattage use comparable amounts of energy, and microwave ovens use substantially less energy than conventional ovens.
Microwave is electromagnetic radiation. It's just radio at frequencies above 3 GHz.
Sound energy is actually a mechanical energy.
No. Total energy is always conserved, but not so mechanical energy.
No, when it is not in use, the microwave would not have a light on. Why would you want the light on when you are not using it and waste energy?
Yes, microwave uses heat energy. It helps in cooking.
The spring and the mass characteristics of their transmission medium are vital to the transmission of sound and vibration waves.
Microwave takes less time to cook
A motor. If electricity passes through it, the motor rotates(kinetic/potential energy)

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.
Microwaves use radiant energy, so they give off radiant energy.
