For this chemical, the heat of vaporization is 86*104 J/g. The conversion of 25.0 grammes of a chemical at its usual boiling point to a gas at 1 atmosphere of pressure requires the addition of 34,400 joules.
A phase transition from the liquid phase to the vaporization phase occurs when an element or molecule vaporization.
Evaporation and boiling are the two methods of vaporization. Boiling is a bulk phenomenon, whereas evaporation occurs on the surface.
The force perpendicular to an object's surface that is delivered per unit area over that force is known as pressure (symbol: p or P). The gauge pressure, also known as gauge pressure, is the pressure in relation to the surrounding air pressure.
