A gas is enclosed in a container fitted with a piston of cross sectional area 0.150 m^2. The pressure of the gas is maintained at 6000 Pa as the piston moves inward 20.0 cm.
A: Evaluate the work done by the gas.
B: If the internal energy of the gas decreases by 8.0 J, Compute the amount of heat removed from the system by heat during the compression.
