How is vapour pressure of a liquid related to the intermolecular forces between molecules and the temperature?

Answer:
The pressure exerted by a vapour in equilibrium with its solid or liquid phase is called vapour pressure.
 
Vapour pressure increases with temperature.
  • At higher temperature more molecules have the necessary kinetic energy to escape the intermolecular force of attraction of the liquid phase.
  • As the temperature increases, vapour pressure increases and intermolecular force of attraction decreases.
  • The more molecules in the vapour phase, the higher the vapour pressure.
The temperature at which vapour pressure becomes equal to atmospheric pressure is called boiling point.
