A system is changed from state A to state B by one path and from B to – InterviewSolution

1.	A system is changed from state A to state B by one path and from B to A another path. If E_(1) and E_(2) are the correspondingchanges in internal energy, then
Answer» `E_(1)+E_(2)=-ve` `E_(1)+E_(2)=+ve` `E_(1)+E_(2)=0` None of these Solution :`DeltaE=0` for a cyclic process.
