Each step in any energy conversion process will _____. gain energy create energy dissipate energy destroy energy

Answers

The correct answer is to dissipate energy. Each step in any energy conversion process will dissipate energy. The energy conversion is the process in which a form of energy is being converted into a new or another form of energy.

The correct answer to the question is : Energy dissipate.

EXPLANATION:

Before coming into any conclusion, first we have to understand law of conservation of energy.

As per law of conservation of energy, energy can neither be created nor be destroyed. It can only change from one form to another form, and the total energy of the universe is always constant.

As per the question, there is energy conversion. One form of any energy may be converted into various types of energy. One particular type of energy is not obtained always.

Hence, the correct answer to the question is energy is dissipated during energy conversion.
