Explanation:
Boiling is defined as a process in which vapor pressure of a liquid substance becomes equal to the atmospheric pressure.
During this change liquid and vapors remain in equilibrium and the equation for this change is as follows.

Therefore, when boiling takes place then average kinetic energy of particles in liquid phase equals to the average kinetic energy of particles in vapor phase.
Hence, we can increase the kinetic energy of particles in liquid phase by increasing the temperature because kinetic energy is directly proportional to temperature as follows.
