What is the value of change in internal energy at 1 atm in the process?
`H_(2)O(l,323K)rarrH_(2)O(g,423K)`
Given : `C_(v,m)(H_(2)O,l)=75.0JK^(-1) mol^(-1):" "C_(p,m)(H_(2)O,g)=33.314JK^(-1)mol^(-1)`
`DeltaH_(vap)"ar 373 K"=40.7KJ//mol`

Calculate the change in enthalpy for the following process at 1 atm H_(2)O(1, 50^(@)C) rarr H_(2)O (g, 150^(@)C) given that Delta H_(v) at 100^(@)C is 40.7 kJ mol^(-1) C_(p)(H_(2)O, l) = 75.0 J mol^(-1)K^(-1) C_(p)(H_(2)O, g) = 33.3 J mol^(-1)K^(-1)

Find the entropy change when 90 g of H_(2)O at 10^(@) C was converted into steam at 100^(@) C. [Given C_(P)(H_(2)O)=75.29 JK^(-1)mol^(-1) and Delta H_("vap")=43.932 JK^(-1)mol^(-1) ]

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) The value of ''DeltaH_("fusion")'' at 263 K & 1 atm will be :
