Liquid water freezes at 273K under external pressure of 1atm . The process is at eruilibrium H_(2)O(l)toH_(2)O(S)at 273 Kand 1atm however , it required to calculate the thermodynamic parameters of the fusion process occurring at same pressure and different temperature . Using the following dat ,answer the questions thaat follow: d_(ice)=0.9gm //cc,d_(H_(2)O(l))=1gm //c"c",1L-atm =101.3 J C_(p)[H_(2)O(s)]=36.4JK^(-1)mol^(-1) C_(p)[H_(2)O(l)]=75.3Jk^(-1)mol^(-1) DeltaH_("fusion")=6008.2mol^(-1).Alldataat 273K. DeltaS_("fusion")at 263 K and 1atm will be :
