They contain the same volume of an ideal gas at the same temperature. The mass of the gas is A is mA is that in B is mB. The gas is each cylinder is now allowed to expended isothermally to double the initial volume. The change in the pressure in A and B respectively Δp and 1.5Δp, Then

Two identical containers a and b with frictionless pistons. They contain the same volume of an ideal gas at the same temperature. The mass of the gas is A is mA is that in B is mB. The gas is each cylinder is now allowed to expended isothermally to double the initial volume. The change in the pressure in A and B respectively Δp and 1.5Δp, Then

A gas is heated at a constant pressure. The fraction of heat supplied used for external work is :
