An ideal gas resides in a closed cylinder (diameter is 0.5 ft) with a frictionless piston. The initial conditions are 139 mol of the ideal gas at 25oC. The piston is compressed isothermally to one third of the initial volume. The heat capacity Cv of an ideal gas is 1.5 ∙ R. (a) What is the heat interaction (kJ) for this process? (b) The piston now expands isothermally to 120% of the same initial volume. Will the heat interaction increase, decrease, or stay the same?
