I'm trying to find the specific enthalpy of acetone (vapour, 56°C, 1 atm) from the reference state acetone (liquid, 20°C, 5 atm). There are 4 paths in the process and I've already figured out how to solve 3 of them. I'm just stuck on this one (first path):
Ac (liquid, 20°C, 5 atm) → Ac (vapour, 20°C, 1 atm)
Since there is a change in pressure and the specific volume is constant ( V = 0.0734 L/mol ), the formula I'm using is:
H = VΔP = V (1 atm - 5 atm).
I should then get an answer around 0.0297kJ/mol but I'm a little confused on the steps.1 AnswerEngineering6 years ago
I know that the general formula is p = γh and for this question, it's γ = p / (29.3)(273+20). But where does the 29.3 value come from?

The temperature of the earth’s atmosphere drops about 5°C for every 1000 m of elevation above the earth’s surface. If the air temperature at ground level is 15°C and the pressure is 760 mmHg, at what elevation is the pressure 380 mmHg? Assume that the air behaves as an ideal gas.1 AnswerPhysics7 years ago
