Question

why does the temperature of a substance remain constant during the change of state

Answer 1

the temperature of substance remains constant during the change of state for example when an object is heated and it is changing state from solid to liquid when it is melting the subsequent heat we apply afterwards gets absorbed by the body as latent heat or hidden heat there are two types of latent heat latent heat of fusion and latent heat of vaporization latent heat of fusion states that the energy required change 1 kg of solid at one atmospheric pressure to liquid is known as latent heat of fusion latent heat of vaporization states that the amount of heat required to turn 1 kg of liquid at one atmospheric to gas is known as latent heat of vaporization this letter it it is needed to break the force of attraction between the particles and as there are broken the body absorbs heat and they absorb heat get evaporated And The Monster field school so the energy required is utilised
