One pound of nitrogen as an ideal gas expands isothermally at 70 F from a volume of 1 ft3 to a volume of 2 ft3. During this process there is heat transfer to the gas from a single reservoir (the surrounding atmosphere) and the gas does work. Evaluate the work and heat transfer for the process, in Btu. Is this process a violation of the Kelvin-Planck statement of the second law of thermodynamics? Explain why or why not.
