    Select Question Language :


    A vertical hollow cylinder contains an ideal gas. The gas is enclosed by a 5 kg movable piston with an area of cross–section 5 x 10–3 m2. Now, the gas is heated from 300 K to 350 K and the piston rises by 0.1 m. The piston is now clamped at this position and the gas is cooled back to 300 K. Find the difference between the heat energy added during the heating process and the energy lost during the cooling process. (1 atmospheric pressure = 105 Nm–2 and g = 10 ms–2)
