Answer 1

Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere. 

Answer 2

Boiling is defined as a phase transition from the liquid state to the gas state, usually occurring when a liquid is heated to its boiling point. At the boiling point, the vapor pressure of the liquid is the same as the external pressure acting upon its surface.
