Why does microwave work except no heat?
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.
Why does a paper plate containing a potato doesnot heat up in microwave oven?
A microwave oven MAINLY heats hydrogen atoms, thus it warms water. A dry paper plate is less affected than most food, but beware of a wet plate.
What happens when you heat food on a glass plate?
If you put a fire under a glass plate or even put a glass plate in the oven it will heat up and break. Depending what is on the top of that plate it will more than likely catch on fire. If you're referring to the microwave then the food will get nice and hot.
Why are there cold spots in microwaves?
The microwave probably couldn't reach the spots. Maybe you could put something inside to heat it up, hot water? You could remove the plate and reheat the microwave before you cook food.
