Answer 2

Answer:

In any physical or chemical process, the total energy remains unchanged.

Energy can neither be created or destroyed but can be changed from one form to the other form.

Energy is consumed some times and released some times in a chemical reaction.

Potential energy in converted to kinetic energy in physical reaction.
