Question 1
During perspiration,
◦ the entropy of the water evaporated increases and the entropy of the body decreases.
◦ the entropy of the water evaporated decreases and the entropy of the body decreases.
◦ the entropy of the water evaporated increases and the entropy of the body increases.
◦ the entropy of the water evaporated decreases and the entropy of the body increases.
Question 2
A hot penny is dropped into cold water inside a polystyrene foam cup. Assuming negligible heat loss to the atmosphere and the cup,
◦ the entropy of both the penny and the water increases.
◦ the decrease in entropy of the penny is more than the increase in entropy of the water.

Spenny ∣ > ∣ Δ
Swater ∣
◦ the decrease in entropy of the penny is equal to the increase in entropy of the water.
∣ Δ
Spenny ∣ = ∣ Δ
Swater ∣
◦ the decrease in entropy of the penny is less than the increase in entropy of the water.
