Kinetic theory can be used to explain some processes such as boiling, evaporation, and melting.
1. Boiling:
When a liquid is heated, the particles of the liquid (e.g. water) gain energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More, and this additional energy makes the particles move faster than before.
As the particles acquire greater kinetic energy, bubbles of vapour form in the liquid and rise to the surface. At this point, the liquid is said to boil and the temperature at which this happens is called the Boiling Point of the liquid.
