1) Consider 2 moles of a onoatomic ideal gas (Cv,m=3R/2) at an initial pressure of 2.0 atm and an initial temperature of 298 K. Assume it expands adiabatically and reversibly until its volume doubles. calculate the expansion ork, the final tmperature of the gas and \DeltaU for the process. What would be the work done if the expansion occurs irreversibly against an external pressure of pext = pf?

2)2 moles of an ideal gas, for which Cv,m = 3R/2, initially at 30.0 C and 1.00 x 10e6 Pa undergoes a two-stae transfrmation. For each of the stages described in the following list, calculate the final pressure, as well as q, w, \DeltaU, and \DeltaH for the complete process.

a)the gas is expanded isothermally and reversibly until the volume triples

b)beginning at the end of the first stage, the temperature is raised to 80.0 C at onstant volume
