Why does the temperature remain constant during the boiling of water even though heat is supplied contivuously ?
Why does the temperature remain constant during the boiling of water even though heat is supplied contivuously ?
Latent Heat of vaporization: When a material in a liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called latent heat of vaporization. There is no need to gain or lose heat energy, therefore the temperature remains constant.
This heat supplied is absorbed by the water particles and this heat increases their kinetic energy. Thus, because of an increase in kinetic energy, the bond between the water particles are cut down and they move more freely, compared to water. Hence, they become gas. So, this is why the temperature remains constant even though heat is supplied continuously to the water.
