What is the entropy change of an engine that operates at 100^@C when 453.6 k.cal of heat is supplied to it?

Latent heat of vaporisation of the water at normal boiling point is 40.75 kJmol^-1 . Calculate the change in entropy of vaporisation.

What is meant by the entropy change of a system in a chemical reaction?

If the enthalpy change for the transition of liquid water to steam is 300 kJ mol^-1 at 27^@C , the entropy change for the process would be

Calculate (1) the enthalpy change in the fusion of 100 g ice at 0^(@)C temperature and 1 atm pressure pressure (2) the enthalpy change in the vaporisation of 10g water at 100^(@)C temperature and 1 atm pressure. Givenn : Latent heat of ice at 0^(@)C temperature and 1 atm pressure =6.02kJ*mol^(-1) and latent heat of vaporisation of water at 100^(@)C temperature= 40.4kJ*mol^(-1) .

At STP if latent heat of fusion of ice is 6 kJ * mol^(-1) , then find out the entropy change of fusion of ice .
