2. 0.0107 mol of nitrogen (diatomic ideal gas, Cp = 7R/2) is expanded in a piston-cylinder assembly from an initial volume of 210 cm to a final volume of 430 cm. The initial temperature of the nitrogen is 40 C. Assume the expansion is done reversibly, meaning there are no frictional losses. Determine the properties listed in the table below for three cases: a. the expansion is done isobarically b. the expansion is done isothermally c. the expansion is done adiabatically
