A
Explanation
The process where a liquid turns spontaneously into vapor is called "evaporation." Evaporation occurs when the molecules at the surface of a liquid gain enough energy to break their intermolecular bonds and escape into the gaseous phase. This process is temperature-dependent and happens at any temperature, not just at the boiling point of the liquid. Boiling, on the other hand, is a related process but occurs throughout the entire liquid when it reaches its boiling point. Evaporation, in contrast, occurs only at the liquid's surface.
