Which process is gas to liquid?

Which process is gas to liquid?

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

Answer: (C)

Condensation is the change from a gas to a liquid. When a vapor loses enough energy (through cooling or increased pressure), the moving molecules slow down and are drawn together by intermolecular forces, forming a liquid. You see this in dew forming on grass or fog settling on a cold surface. The other processes involve different direction changes: vaporization is liquid to gas, melting is solid to liquid, and sublimation is solid to gas.
