MCQ
When a system is taken from state $i$ to state $f$ along the path $iaf$, it is found that $Q=50$ $cal$ and $W=20$ $cal$ Along the path $ibf\ Q = 36\ cal. \ W$ along the path $ibf$ is ....... $ cal$
- A$14$
- ✓$6$
- C$16$
- D$66 $
✓
Answer
Correct option: B.
$6$
b
For path iaf,$\Delta U = Q - W = 50 - 20 = 30\,cal.$
For path iaf,$\Delta U = Q - W = 50 - 20 = 30\,cal.$
For path ibf $W = Q - \Delta U = 36 - 30 = 6\,cal.$
