During any process involving a heat transfer, the entropy of a system must always increase, it can never decrease.

True or False?

True

Explanation:

Entropy is a thermodynamic variable that always increases or remains constant, but does not decrease.

This indicates that energy is always transferred from a higher temperature system to a lower temperature system and not the other way around.

Entropy can also be thought of as what drives a system into equilibrium, and systems reach equilibrium through heat transmission.

The fact that the entropy of a closed system never decreases is a statement of the second law of thermodynamics.
