Question

for any substances,why does the temperature remain constant during the change of state?

energy is used in the transformation of state
also called latent heat

Answer 2

Hi friend!!

During the change of state, the temperatures doesn't rise and remains constant..
This is because the change of state takes away the latent heat from a body. So no extra rise in temperature is required for the change of state i.e for the molecules to break apart the forces of attraction holding it together...

Hope that helps you!!
