Which process is the change from a gas to a liquid?

• A. Vaporization
• B. Conduction
• C. Condensation
• D. Convection

Answer: (C)

Condensation is the change of a gas into a liquid. It happens when gas molecules lose enough energy, usually by cooling, so they slow down and come closer together to form a liquid. Think of steam turning into water on a cold surface or dew forming on grass—that’s condensation. Vaporization would be the opposite process (liquid to gas). Conduction is heat transfer through direct contact, and convection is heat transfer by the movement of a fluid.
