What term describes the change of a liquid into a gas?

• A. Evaporation
• B. Condensation
• C. Deposition
• D. Sublimation

Answer: (A)

The change from a liquid to a gas is evaporation. It happens when molecules at the surface gain enough energy to overcome the attractive forces holding them in the liquid and escape into the air as gas. Evaporation can occur at temperatures below the liquid’s boiling point and mainly occurs at the surface, making it a slower, continuous process compared to boiling. You can see it in everyday life when a puddle dries up or clothes dry after washing. Condensation is the reverse process (gas to liquid), deposition is gas turning directly into a solid, and sublimation is a solid turning directly into a gas.
