Text Solution

Verified by Experts

Work is not a state function.
One state of a system can be changed to another in a several ways. Work involved in different paths differ in their quantity.
Work depends on the path of the reaction but not on the state of the system.
Work is dependent on the capacity factor and intensity factor.
