One mole of an ideal gas, initially at 30°C and 1 bar, undergoes the following mechan- ically reversible changes. It is compressed isothermally to a point such that when it is heated at constant volume to 120°C its final pressure is 12 bar. Calculate Q, W, AU, and AH for the process. Take Cp = (7/2)R and Cy (5/2)R.
