The law of thermodynamics states that every time energy is transformed from one form to another, some of that energy is converted to heat. that means there is never 100% conversion of one form of energy to another. because is not available to do , the usable amount of energy is each time an energy conversion occurs.

Explanation:

The Second or the Entropy  law of thermodynamics states that every time energy is transformed from one form to another, some of that energy is converted to heat. That means there is never 100% conversion of one form of usable energy to another. Because Heat is not available to do work , the usable amount of energy is wasted each time an energy conversion occurs.
