What is the term for the process in which liquid water turns into vapor?

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

Answer: (B)

The term for the process in which liquid water turns into vapor is evaporation. This process occurs when molecules in liquid water gain enough energy to overcome intermolecular forces and escape into the air as gas. Evaporation typically happens at temperatures below the boiling point, and it can take place at any temperature, as long as there is energy supplied to the water molecules, such as heat from the surrounding environment. In the context of the other options, condensation refers to the opposite process where vapor turns back into liquid water, typically occurring when warm air cools and loses energy. Precipitation refers to any form of water, such as rain or snow, that falls from clouds to the ground and is not related to the phase change of liquid water becoming vapor. Sublimation involves a solid turning directly into a vapor without going through the liquid state, such as dry ice changing into carbon dioxide gas, and is not applicable to the conversion of liquid water.
