Question

When dry ice goes through sublimation, the entropy increases.
A) True
B) False

Answer 1

The statement that entropy increases when dry ice undergoes sublimation is true. Sublimation causes a solid to transition directly into a disordered gas state, increasing entropy.

Step-by-step explanation:

When dry ice goes through sublimation, the entropy increases. This statement is True. Sublimation is the process by which a solid substance transitions directly into a gaseous state without going through a liquid phase. Dry ice, which is solid carbon dioxide, undergoes sublimation at -78.5°C (-109°F). During sublimation, the highly ordered solid structure is converted into a much less ordered gas, significantly increasing the disorder of the molecules.

This increased disorder is associated with an increase in entropy, which is a measure of the systemic disorder or randomness. Therefore, the change in entropy during the sublimation of dry ice is positive, indicating an increase in entropy.
