What term describes liquids and solids that turn into gas?

• A. Condensation
• B. Oxidation
• C. Vapor
• D. Sublimation

Answer: (C)

Vapor describes the gas form of a substance that came from a liquid or a solid. When liquids vaporize (boil or evaporate) or solids sublime, the resulting gas is called a vapor. The term is about the state of matter—the gas phase—regardless of whether it originated from a liquid or a solid. Condensation is the opposite process (gas becomes liquid), oxidation is a chemical reaction with oxygen, and sublimation is a solid turning directly into gas; those describe different processes or states, not the general gas form produced by vaporization.
