Three moles of an ideal gas (with temperature-independent C P = (7/ 2)R, C V = (5/2)R)

Question:

Three moles of an ideal gas (with temperature-independent C_P = (7/ 2)R, C_V = (5/2)R) is contained in a horizontal piston/cylinder arrangement. The piston has an area of 0.1 m² and mass of 500 g. The initial pressure in the piston is 101 kPa. Determine the heat that must be extracted to cool the gas from 375°C to 275°C at:

(a) Constant pressure;

(b) Constant volume.
