Answer
The change from the liquid state to gaseous state on heating at a constant temperature is called boiling.
When a liquid is heated the average kinetic energy of the liquid molecules increases. When the molecules acquire sufficient kinetic energy to overcome the force of attraction of other molecules, they escape out in form of vapour throughout the mass of liquid and not just it's surface.
