"Conservation of energy" refers to the fact that _____.
Agata [3.3K]

Answer: Option (b) is the correct answer.

Explanation:

According to the law of conservation of energy, it is known that energy can neither be created nor it can be destroyed.

But energy can be changed from one form to another.

Whereas entropy is the degree of randomness present within the molecules of a substance or object.

For example, gas molecules are able to move rapidly so, they have more entropy as compared to solid and liquid substances.

According to second law of thermodynamics, entropy of the system is always increasing.

Thus, we can conclude that "Conservation of energy" refers to the fact that energy cannot be created or destroyed but can be converted from one form to another.
