Question

Which of the following phase changes only occurs in solids possessing vapor pressures above atmospheric pressure and at ambient temperature?

Condensation

Melting

Sublimation

Deposition

Answer 1

Sublimation would be when a solid goes straight to a gas skipping the liquid phase. I'm guessing that would be the answer!

Answer 2

Answer: Sublimation

Explanation:

Sublimation can be defined as the phenomenon by which there is a phase change in between solid and gas.

When ambient temperature and atmospheric pressure is provided to solids, then solids directly evaporate to form gas without being converted into gas.

Hence, the correct answer is option C
