Second law of thermodynamics

Assignment Help Mechanical Engineering
Reference no: EM13873460

A piston/cylinder contains helium at 110 kPa at ambient temperature 20oC, and initial volume of 20 L. The stops are mounted to give a maximum volume of 25 L and the nitrogen line conditions are 300 kPa, 30oC. The valve is now opened which allows nitrogen to flow in and mix with the helium. The valve is closed when the pressure inside reaches 200 kPa, at which point the temperature inside is 40oC. Is this process consistent with the second law of thermodynamics?
