प्रश्न
Explain the following:
The heat supplied to a substance during it change of state, does not cause any rise in its temperature.
उत्तर
Heat supplied to a substance during its change of state, does not cause any rise in its temperature because this is latent heat of phase change which is required to change the phase only.
