If the system goes from two different paths to the same final state then the change in internal energy for both systems is _.
Correct answer: A. Same
- A. Same
- B. Different
- C. May be same
- D. Not enough information
Explanation
The change in internal energy if a system depends only on initial and final states of the system and not on path followed .

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
