Fill in the blank spaces by choosing the correct words from the list given below: latent heat of fusion, melting point, steam, constant, latent heat of vaporisation. The amount of heat required to change 1 g of a substance at its melting point into liquid state without any rise in temperature is called specific_________.

DeltaH_("fus") is the latent heat of melting and T_("fus") is the melting point, then entropy of melting is

Enthalpy of fusion of water is 6.01 kJ mol^(-1) . The entropy change of 1 mole of ice at its melting point will be:
