The direct change of state from vapor to liquid is called?

• A. Sublimation
• B. Fusion
• C. Vaporization
• D. Condensation

Answer: (D)

Condensation is the process by which a vapor becomes a liquid. When a gas loses enough energy or experiences higher pressure, its molecules slow down enough that the attractive forces pull them together into a dense, liquid state. This is the opposite of vaporization, which is liquid turning into gas. Sublimation is gas turning directly into a solid, skipping the liquid phase, and fusion (melting) is solid turning into a liquid. So the direct change from vapor to liquid is condensation.
