1. Consider an ideal gas that has initial pressure and volume pi, Vi, and undergoes isothermal expansion to volume Vf. Find the following in terms of pi, F, and Vf:
(a) the work done by the gas;
(b) the final pressure, pf.
2. An ideal gas whose molecules each have five degrees of freedom has initial pressure and volume pi, 6. If this gas undergoes adiabatic expansion to volume Vf, find the following in terms of pi, 6, and Vf:
(a) the work done by the gas;
(b) the final pressure, pf
