When something sublimes (Goes straight from solid to gas), it takes in energy, as it is an endothermic process, so its entropy increases

Answer: (2) increases

Explanation: Entropy is the measure of randomness or disorder of a system. More is the random arrangement of molecules in a system , more is the entropy of the system. More ordered is the arrangement of molecules in a system, less is the entropy of the system.

When carbon dioxide sublimes, it means solid carbon dioxide is directly changing to gaseous state without undergoing into liquid state, thus the molecules will be more random and thus the entropy will increase.
