Question

For any substance, why does temperature remain constant during change of state?

Answer 1

Answer:The heat energy is utilised in breaking the molecular bond

State of a matter is changed when the space between two particles of the atom increases or we can say the intermolecular force of attraction weakens then it is converted into solid to liquid,liquid to gas vice versa

when we heat the matter the heat energy is utilised in changing of the state so the is no increase in temperature at that time

Hope U Understand!

Answer 2

Hey!

It is due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant.
