Concept introduction:

The various kinds of interactions that bind a molecule to another are known as intermolecular forces. These interactions can be dispersion, dipole–dipole, ion–dipole, and hydrogen bonding. When the state of a molecule is changed, the intermolecular forces are to be broken.

In a closed system, the pressure exerted by vapors or gas on a solid or liquid at a particular temperature is called vapor pressure. It is also an indicator of the evaporation rate of the liquid. The common unit of vapor pressure is Pascal (Pa).
