Which process is gas turning into liquid?

Which process is gas turning into liquid?

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

Answer: (A)

Condensation is the process where a gas becomes a liquid. When a gas like water vapour cools down or is compressed, its molecules lose energy and move more slowly. The stronger intermolecular forces pull them together, forming a liquid. You can see this in everyday life as dew on grass or fog on a cold mirror—the vapour in the air loses enough energy to turn into liquid droplets. This release of energy accompanies condensation, which is the opposite of boiling (liquid to gas). Sublimation and deposition are solid–gas and gas–solid changes, respectively, not gas–liquid.
