In Equation (8.16), (dP/dT) vaporization was calculated by assuming that V gas m >> V liquid m
Question:
In Equation (8.16), (dP/dT)vaporization was calculated by assuming that V gas m >> V liquid m. In this problem, you will test the validity of this approximation. For water at its normal boiling point of 373.12 K, ΔH vaporization = 40.656 × 103 J mol-1,Pliquid = 958.66 kg m-3, and Pgas = 0.58958 kg m-3. Compare the calculated values for (dP/dT)vaporization with and without the approximation of Equation (8.19). What is the relative error in making the approximation?
