Figure shows a cylindrical container containing oxyegn (gamma = 1.4) and closed by a 50 kg frictionless piston. The area of cross section is 100cm(2) , atmospheric pressure is 100 kPa +E2 and g is 10 m s^(-2) . The cylinder is slowly heated for some time. Find the amount of heat supplied to gas if the piston moves out through a distsnce of 20 cm. .

A vertical cylinder of height 100cm contains air at a constant temperature. The top is closed by a friction less light piston. The atmospheric pressure is equal to 75 cm of mercury. Mercury is slowly poured over the piston. Find the maximum height of the mercury column that can be put on the piston.
