The change in specific enthalpy during the melting of ice at 0 degrees C and 1.01 X 10^5 Pa is ?h= 333.39 kj/kg. Consider a system of ice and water at 0 degrees C of ice and water at 0 degrees C and 1.01 X 10^5 Pa, in contact with a heat reservoir at 20 degrees C. Foir the process of melting 2kg of ice under these conditions, find the change in entropy of
a) the system?
b) the reservoir?
c) the universe?
