R heat of fucion
Several of these properties are the vapor pressure, the heat of vaporization, and the boiling point of a liquid.
The scientific term for the conversion of a liquid to a gas or vapor below its boiling point is vaporization.
The rate of evaporation of a liquid in an open container increases with the addition of heat.
A liquid evaporates faster when heated because the kinetic energy of its particles increases.
The boiling point (bp) is the temperature at which the vapor pressure of the liquid is just equal to the external pressure.
The boiling point of a liquid at a pressure of 1 atm is the normal boiling point
