A sample of gas has its volume reduced isobarically from 3 L to 1 L inside a vertical cylinder with a movable piston at a pressure of 1.25 atm. The gas temperature decreases by 10 °C and its internal energy by 1000 J. What is the heat exchanged (Q) during the process if (i) the gas is ideal, or (ii) the gas is not ideal?
