Hello friend
Here's your answer
Water starts boiling at 100°C temperature. After attaining that temperature, even with the supply of heat, there will be no rise in the temperature. All the heat that is supplied is utilized by the molecules of water to overcome the force of attraction between them and change into vapour. So there will be no change in the temperature. This is called latent heat of vaporisation. After changing into vapour there will be a change in temperature.
Hope it helps!

Because the boiling point of water is 100°C and the extra heat is used to breakdown the intermolecular force of attraction between particles of water
