Question

What happens when a liquid is supplied with heat?

Answer 1

when we apply heat to liquid, it change its state from liquid to vapour by evaporation

Answer 2

Hello ayush

When heat is supplied to a liquid, it is absorbed by the molecules in that liquid to overcome the force of attraction between them and change into gaseous state. The heat is absorbed in the form of latent heat of vaporisation. At that instance there will be no rise in temperature even though the heat is being supplied. That heat is utilised to change the liquid into vapour. Once the liquid gets converted into vapour the temperature starts rising.
