What is the difference between work of expansion and work of compression?

Compression will have positive work on the gas whereas expansion will have negative work on the gas.

Work of expansion occurs when the gas is doing work on an object(s), such as a piston, and work of compression occurs when an object(s) is doing work on the gas. Work of expansion has a negative sign and work of compression has a positive sign.

Work of expansion indicates work being done by the reaction onto the system. Since the flow of energy is from the reaction to the system, we know the reaction is doing work.

work of expansion will be a negative value because the change in volume is positive, while work of compression will be a positive value because the change in volume is negative.
