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.
∣ ΔSpenny ∣ > ∣ ΔSwater
◦ the decrease in entropy of the penny is equal to the increase in entropy of the water.
∣ ΔSpenny ∣ = ∣ ΔSwater
◦ the decrease in entropy of the penny is less than the increase in entropy of the water.
∣ ΔSpenny ∣ < ∣ ΔSwater
