According to the second law of thermodynamics, energy is never 100% efficient because some of the energy disperses as heat. 

Answer: The correct answer is first; some of the energy disperses as heat.

Explanation:

First law of thermodynamics states that energy is always conserved in a system which means that energy can neither be created, nor be destroyed but it can only be transformed from one form to another.

Second law of thermodynamics states that all spontaneous processes are accompanied by increase in entropy or randomness.

Hence, the correct answer is first; some of the energy disperses as heat.
