Q2/ One mole of an ideal gas, initially at 303.15 K (30°C) and / bar, is changed to 403.15 K (130°C) and 10 bar by three different mechanically reversible processes: 1- The gas is first heated at constant volume until its temperature is 403.15 K ( 1 30°C); then it is compressed isothermally until its pressure is 10 bar. 2- The gas is first heated at constant pressure until its temperature is 403.15 K (130°C); then it is compressed isothermally to 10 bar. 3- The gas is first compressed isothermally to 10 bar, then it is heated at constant pressure to 403.15 K (130°C). Calculate Q. W, AU, and AH in each case. Take Cp= (7/2)R and Cv= (5/2)R. Altematively, take Cp = (5/2)R and Cv = (3/2)R.where b and R are positive %3D constants.
