What do we call the change of state from gas to liquid?

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

Answer: (B)

The change of state from gas to liquid is called condensation. This process occurs when gas particles lose energy and come closer together, resulting in a transition to the liquid state. For example, when water vapor in the air cools down, it condenses into liquid water, forming droplets on surfaces or contributing to cloud formation. In contrast, evaporation refers to the process where a liquid turns into gas, while sublimation describes the transition of a solid directly into a gas, bypassing the liquid state entirely. Addition does not pertain to any specific change of state; rather, it is a term generally used to describe the act of adding something. Understanding these processes is crucial in recognizing how matter behaves under different conditions.
