Answer to Question #330858 in Chemistry for grey tyrant

Question

Calculate the entropy change, So for the following process.

a. Melting of ice at 0°C (heat of fusion of ice is 6.02 kJ/mol)

Answer 1

The entropy of the system, which is δQ/T, increases by δQ/273K. The heat δQ for this process is the energy required to change water from the solid state to the liquid state, and is called the enthalpy of fusion, i.e. ΔH for ice fusion.
