MCQ
Which of the following is correct option for free expansion of an ideal gas under adiabatic condition?
- A$q = 0, \Delta T \ne 0, W = 0$
- B$q \ne 0, \Delta T = 0, W = 0$
- ✓$q = 0, \Delta T = 0, W = 0$
- D$q = 0, \Delta T < 0, W \ne 0$
✓
Answer
Correct option: C.
$q = 0, \Delta T = 0, W = 0$
c
For an ideal gas, for free expansion $q=0 ; \Delta T=0$ and $W=0$
For an ideal gas, for free expansion $q=0 ; \Delta T=0$ and $W=0$
