Question

In an open system, for maximum work, the process must be entirely

Answer 1

Explanation:

The maximum work is done when the external pressure Pext of the surroundings on the system is equal to P, the pressure of the system. If V is the volume of the system, the work performed as the system moves from state 1 to 2 during an isobaric thermodynamic process, W12, is the maximum work as given by Eq.
