Question

write the Concept of maximum work ​

Answer 1

Answer:

the amount of work performed by a system is governed by the opposing force (Pext). Larger the opposing force more work is done by the system to overcome it.

If the opposing force is zero no work is involved. With an increase of the opposing force from zero, more work will be needed by the system. When the opposing force reaches its maximum the system performs maximum work. With an opposing force being greatest more effort would be needed to overcome it

Answer 2

Answer:

For all thermodynamic processes between the same initial and final state, the delivery of work is a maximum for a reversible process. The principle of work was a precursor to the development of the thermodynamic concept of free energy.
