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.

Ne has a mass of 20.18 amu, N2 has a mass of 28.01 amu, H2 has a mass of 1.01 amu, Ar has a mass of 39.95 amu, and He has a mass of 4.00 amu.
isothermal process is a process where there will be no change in the temperature so we say change in temperature during isothermal process will be constant
during adiabatic process no heat exchange take place i.e
