What is the name of the process by which a liquid turns into a gas?

• A. Condensation
• B. Evaporation
• C. Freezing
• D. Precipitation

Answer: (B)

The process by which a liquid turns into a gas is known as evaporation. This phenomenon occurs when molecules in a liquid gain enough energy, usually from heat, to overcome the intermolecular forces holding them together. When this happens, they escape into the air as gas. Evaporation typically takes place at the surface of the liquid and can occur at any temperature, although it is faster at higher temperatures where more molecules possess the energy necessary to transition to the gas phase. This is a vital process in the water cycle, influencing weather patterns and playing an essential role in various natural and industrial processes. Understanding evaporation is crucial for grasping concepts related to temperature changes, humidity, and even the mechanisms of certain cooling technologies.
