8.1 g of Ar are confined in a 8.0 L container at 310 K. The gas is expanded adiabatically and reversibly until the volume increases by a factor of two. (A) Find the temperature change for this process. You may assume that Ar behaves like a perfect gas under these conditions. (B) Assume that the gas had been expanded isothermally and reversibly instead. Would more work have been done in that case or less? Explain your answer by using an appropriate graph as part of the answer.
