What happens inside water molecules if heat is added when water boils?
The energy is stored in the form of potential energy; therefore, the temperature doesn't increase
The energy is added as kinetic energy; therefore, the molecules move faster
The energy is stored as potential energy; therefore, the molecules move faster
The energy is added as kinetic energy; therefore, the temperature increases
All options are correct

Water boils at 100∘C. If we add more heat to boiling water, then it is used to convert to vapour and its potential energy increases. But the temperature doesn,t increase above 100∘C.
