What is the process of gas turning into a liquid?

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

Answer: (B)

Condensation is the process where a gas loses enough energy to become a liquid. When gas molecules cool down or are compressed, they slow down and come closer together, forming a liquid and releasing energy in the process. A familiar example is water vapor in the air turning into liquid water on a cool surface or forming clouds. The other transformations involve different directions of phase change: evaporation is liquid turning into a gas, sublimation is solid turning into a gas, and deposition is gas turning directly into a solid.
