Agas is inside a cylinder fitted with a piston. the gas and its surroundings are both at 20 ∘c and the gas is compressed as the piston moves and decreases the cylinder volume. the compression takes place slowly enough to allow the gas temperature to stay at 20 ∘c and the work done on the gas by the compression is 2.4 × 103 j.
