A cylinder of ideal gas is closed by an 8 kg movable piston of area 60cm^2. The atmospheric pressure is 100 kPa. When the gas is heated from 30^@ C to 100^@ C the piston rises 20 cms. The piston is then fastened in the place and the gas is cooled back to 30^@ C. IfDelta Q_1 is the heat added to gas during heating and Delta Q_2 is the heat lost during cooling, find the difference.
