Question

0.4 m3 of gas at 15 bar and 120°c expanded adiabatically until, its pressure reaches 6 bar. It is than compressed iso-thermally to its original volume. Find the final temperature and pressure of the gas. Also determine the change in internal energy. Take Cp = 1.005 kJ/kg K, Cv = 0.718 kJ/kg K

Answer 1

Answer:

an adiabatic process (Greek: adiábatos, “impassable”) is a type of thermodynamic process that occurs without transferring heat or mass between the thermodynamic system and its environment. Unlike an isothermal process, an adiabatic process transfers energy to the surroundings only as work
