Question:
Air as an ideal gas expands isothermally at 20°C from a volume of 1 m3 to 2 m3 . During this process there is heat transfer to the air from the surrounding atmosphere at 25°C, modeled as a thermal reservoir, and the air does work. Determine the work and heat transfer for the process, in kJ/kg. Is this process in violation of the second law of thermodynamics? Explain.
