A rigid tank is divided by a membrane into two compartments containing the same ideal gas at pressures P1=5 bar and P2=1 bar, both at temperature T=300 K. The membrane ruptures, allowing the gases to mix and reach equilibrium. A student claims this process could be made reversible by replacing the membrane with a frictionless, massless piston that moves slowly until pressure equilibrium is reached. Evaluate this claim.
