Consider the figure below where a cylinder of an ideal gas is closed by an 16 kg movable piston of area = 60 cm2. When the gas is heated from 30 0C to 100 0C the piston rises by 20 cm. The piston is then fastened in place and the gas is cooled back to its original temperature of 30 0C. Find the difference in heat between the heating process (∆Q1 ) and the cooling proecess (∆Q2 ); ∆Q1 -∆Q2 . The picture has a piston on gas in a container(like a syringe).
