Define State of a system.

Assertion : In a process, if work = 0 then DeltaU = q Reason : q is difference between initial state and final state of a system.

When the state of a system changes from A to B adiabatically the work done on the system is 322 joule. If the state of the same system is changed from A to B by another process, and heat required is 50 calories of heat is required then find work done on the system in this process? (J = 4.2 J//cal)
