MCQ
The work done by a system is $8$ joule, when $40$ joule heat is supplied to it. What is the increase in internal energy of system......$J$
- A$25$
- B$30$
- ✓$32$
- D$48 $
✓
Answer
Correct option: C.
$32$
(c)$q = 40\,J$
$w = - 8\,J$ (work done by the system)
$\Delta E = q + w = 40 - 8 = 32\,J$.
$w = - 8\,J$ (work done by the system)
$\Delta E = q + w = 40 - 8 = 32\,J$.
