Question

\conservation of energy\ refers to the fact that ___.
the net amount of disorder is always increasing
energy cannot be created or destroyed but can be converted from one form to another
no chemical reaction is 100 percent efficient
the entropy of the universe is always increasing
if you conserve energy you will not be as tired

Explanation:

The law of conservation of energy states that energy cannot be created or destroyed. It can only change forms. For example, potential energy can convert to kinetic energy. The first option refers to the second - law of thermodynamics (increase in disorder/entropy). The third option is about reaction efficiency. The fourth is also related to entropy (second - law). The fifth is a non - scientific, layman's misinterpretation.

Answer:

energy cannot be created or destroyed but can be converted from one form to another
