Question

To cook food, a microwave oven converts electrical energy into ________ energy. A) electromagnetic B) heat C) mechanical D) nuclear

Answer 1

Answer: Option (B) is the correct answer.

Explanation:

When we heat food in a microwave then the electrical energy of microwave produces microwaves which are also part of electromagnetic spectrum.

These microwaves are absorbed by food and as a result microwaves change into heat energy. Therefore, food becomes hot.

Thus, we can conclude that to cook food, a microwave oven converts electrical energy into heat energy.
