From 1, the water particles are constantly gaining in thermal energy and the thermal energy will be converted to the internal kinetic energy. This causes the water molecule to move faster. From 2, the water has reached the boiling point of 100 degrees celcius and remain constant. The internal potential energy converted from the thermal energy is used to break the bonds between the liquid state and the gas state. From 3, the liquid particles have broke the bonds between the gas and are in gaseous state. The gas particles move faster and further apart because there is a gain in the intern al kinetic anergy.
