The molar enthalpy of fusion for ice at 0.0°C and a pressure of 1.00 atm is 6.01 kJ, and the molar volumes of ice and water at 0°C are 0.0197 L and 0.0180 L, respectively. Calculate ΔH and ΔU for the melting of ice at 0.0°C.

WebSep 1, 2015 · Without knowing the specific equation of state (aka, if your gas is ideal or not), you can only say d H = C P d T at constant pressure. However, in the specific case of the ideal gas, you know that both H and C P don't depend on P, and so you can apply the equation more generally. I think you meant d H = C p d T. http://cms.ashrae.biz/weatherdata/STATIONS/723060_p.pdf nahb legal action fund
