Question

what is the definition of condensation?
liquid particles gain energy to become a solid.
gas particles lose energy to become a liquid.
liquid particles lose energy to become a gas.

Explanation:

Condensation is a phase - change process. When gas particles lose energy, their movement slows down. As a result, the intermolecular forces become stronger, and the gas particles come closer together to form a liquid.

• The first option “Liquid particles gain energy to become a solid” describes freezing (liquid to solid phase change).
• The third option “Liquid particles lose energy to become a gas” is incorrect as liquid to gas (vaporization) generally requires energy gain (endothermic process in most cases like evaporation).

Answer:

Gas particles lose energy to become a liquid.
