Evaporation occurs only at ______ of a liquid.
Hence, evaporation occurs only at the surface of the liquid.
Evaporation is the change of liquid to the vapor state at any temperature below the boiling point of the liquid. Though both evaporation and boiling represent change of state, but these are different. Whereas evaporation occurs at all temperature, boiling occurs only at a specific temperature known as boiling point temperature. Moreover, evaporation is a surface phenomenon but boiling occurs throughout the liquid including its surface.
