Calculate the adiabatic change in entropy when 3g of ice at -12C is added to 55.0g of hot water at 77C in an isolated system.
Given the following information:
Heat capacity of ice cp[H2O(s)]=37.17JK-1mol-1
Heat capacity of water cp[H2O(l)]=75.29JC-1mol-1.
Molar enthalpy of fusion of ice DHm[H2O(s)]=+6.008kJmol-1
