One mole of an ideal gas, initially at 30 ºC and 1 bar undergoes the following mechanically reversible changes. It is compressed isothermally to a point such that when it is heated at a constant volume to 120 ºC its final pressure is 12 bar. Calculate Q, W, ?U, ?H for the process. Assume CP = 7/2 R and CV = 5/2 R
