Answer to Question #345207 in Chemical Engineering for Devendra

Question

A system is taken from state 1 to state 2 along a path A. During this

process it received 200 kJ energy as heat and does 100 kJ work. If the

system is taken from state 2 to state 1 by a different path B, it is necessary

to spend 150 kJ work on the system. Determine the heat interaction along

the path B. Suppose the system is restored to state 1 from state 2 by an

adiabatic path C, how much work has to the done on the system?
