Liquid water freezes at 273 K under external pressure of 1 atm. The process is at equilibrium `H_(2)O (I) hArr H_(2)O (s)` at 273 K & 1 atm However it was required to calculate the thermodyanamic parameters of the fusion prcess occuring at same pressure & different temperature. Using the following data, answer the question that follow. `d_(\"ice\") = 0.9 gm//c c, d_(H_(2)O(I)) = 1 gm//c c, C_(P) [H_(2)O(s)] = 36.4 JK^(-1) mol^(-1), C_(P) [H_(2)O (I) ] = 75.3 JK^(-1) mol^(-1), Delta H_(\"fusion\") = 6008.2 J mol^(-1)` `\'\' Delta S_(\"fusion\")\'\'` at 263 K & 1 atm will be:
