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^@Cthe piston rises 20 cm. The piston is then fastened in the place and the gas is cooled back to 30^@C. If Delta Q_1is the heat added to the gas during heating and Delta Q_2is the heat lost during lost cooling, find the difference.
