    Maxwell relations with heat capacity

    I am very thankful for your reply. However, I managed to solve the problem several hours after my post. Your method though is something that I didn't think of, so I do appreciate it.

    Maxwell relations with heat capacity

    Homework Statement Use the Maxwell relations and the Euler chain relation to express (ds/dt)p in terms of the heat capacity Cv = (du/dt)v. The expansion coefficient alpha = 1/v (dv/dt)p, and the isothermal compressibility Kt = -1/v (dV/dp)T. Hint. Assume that S= S(p,V) Homework Equations...

    Internal combustion engine problem.

    An internal combustion engine runs on octane, the enthalpy of combustion is -5512 kJ/mol. The mass of 1 gallon of fuel is 3 kg. The engine temperature is 2000 degrees C and the exit temperature is 800 degrees C. What is the work done? The total enthalpy is -145053 kJ. The total number of...
