Question

During perspiration the entropy of the water
А. The entropy of the water evaporated decreases and the entropy of the body decreases.
B. The entropy of the water evaporated decreases and the entropy of the body increases.
C. The entropy of the water evaporated increases and the entropy of the body decreases.
D. The entropy of the water evaporated increases and the entropy of the body increases.

Answer 1

Answer: Option C.

Explanation:

Entropy is defined as a thermodynamic quantity which represents the thermal energy that is not able to convert into mechanical work.

During perspiration, entropy of  body decreases due to evaporation of water which releases energy from our body and allows cooling effect while entropy of  water increases as liquid molecules changes to vapor form that occupy more larger space in the environment.

Hence, the correct option is C.
