Question

An ideal gas, with temperature-independent CP = (7/2)R, at 15°C and having an initial volume of 60 m3, is heated at constant pressure (P = 0.1013 MPa) to 30°C by transfer of heat from a reservoir at 50°C. Calculate ΔSgas, ΔSheat reservoir, ΔSuniverse. What is the irreversible feature of this process?

Answer 1

∆Sgas =3.6244kJ/K

∆Sreservoir=-3.315kJ/K

∆Suniverse = 0.3094kJ/K

The irreversible feature of the process is that The change in entropy of the universe is increased
