The air 10 cm diameter cylinder, as shown below, is heated until the spring is compressed 50mm. Find the work done by the air on the frictionless piston. The spring as the beginning of this process has a displacement of 0.0m with a spring constant of K=10KN/m. (assume Patm=101.325Kpa)

    I don't see your figure, but why isn't the work done on the piston just equal to the final potential eneergy of the spring? You know what that is.
