The unavailable energy is given off as microwaves
The unavailable energy is given off as microwaves

The unavailable energy is conducted

Answer 1

The correct response is:

The unavailable energy is given off as heat.

This relates to the second law of thermodynamics, which states that energy transformations are not 100% efficient, and some energy is often lost as heat, making it unavailable for doing work.
