An insulated rectangular container carrying a gas is filled with a movable piston. The dimension of the piston is 10 {cm} \times 20 {cm} \times 1 {cm}. The density of the material of which piston is made is 8 {g} {cm}^{3}. If the gas expands, lifting the piston by 10 {cm}, what is the change in the internal energy of the gas? [ Take g=10 {m} \/ {s}^{2}]
