Problem- Compute change in H (delta H) and change in S for ice betweeen -10 degrees Celsius and +10 degrees Celsius knowing that
-ice melts at 0 degrees Celsius-the process occurs at constant pressure-Cp [H2O(s)] = 37.0 J*K^-1*mol^-1 is not a function of T-Delta fus H = 6.0 KJ*mol^-1-Cp [H2O(l)] = 76.0 J*K^-1*mol^-1 is not a function of T
Then, compute the value for change in G at the temperature of fusion both theoretically and by substituting the numerical results obtained above. Make a comment on the sign for each of the results (delta S, delta H, delta G)
