MCQ
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 corresponding changes in internal energy, then
  • A
    ${E_1} + {E_2} = - ve$
  • B
    ${E_1} + {E_2} = + ve$
  • C
    None of these

     

  • ✓
    ${E_1} + {E_2} = 0$
✓

Answer

Correct option: D.
${E_1} + {E_2} = 0$
(d) Internal Energy is a state dependent function.
