What is the amount of heat released by cooling 1250 grams of water vapor from 307*C to 20*C at a constant pressure of 1,013*10^5 Pa. If the specific heat of evaporation of water Q(H2O)gas = 2260 J/g. The dependence of the true heat on the temperature for the vapor and the liquid state is expressed by the equations of the form Cp = a + W + C ‘/ T^2 taken from the reference
