Amonatomic, ideal gas is in a sealed container (the number of gas molecules is always constant: n = 2 moles); the initial pressure is pi = 1.01 × 105 pa and the initial volume is vi = 0.0224 m3. first, the volume of the gas is decreased at a constant pressure (at pi = 1.01 × 105 pa) to a final volume of vf = 0.0155 m3. second, the pressure of the gas is increased at a constant volume (at vf = 0.0155 m3) to a final pressure of pf = 1.35 × 105 pa. how much heat was added to (give as a positive number) or removed from (give as a negative number) the system? (the gas constant r = 8.31 j/mole-k.) q =
