Final answer:

When a gas is produced from a solid, the entropy is lower because the number of gas molecules decreases.

Step-by-step explanation:

The answer is negative because the number of gas molecules decreases. Gas molecules have more entropy than liquid molecules since they have more energy in the form of degrees of freedom of motion (translational, rotational, and vibrational). Therefore, fewer gas molecules mean less entropy.
