QNEET-2020-Ch-659: NEET 2020 Chemistry - Class 11 NEET-2020-Ch-659 Solution: The correct option for free expansion of an ideal gas under…
The correct option for free expansion of an ideal gas under adiabatic condition is: q = 0 and w > 0 q < 0 and w = 0 q > 0 and w > 0 q = 0 and w = 0
Multiple Choice Options
- A q = 0, _ T < 0 and w > 0
- B q < 0, _ T = 0 and w = 0
- C q > 0, _ T > 0 and w > 0
- D q = 0, _ T = 0 and w = 0
Step-by-Step Verified Solution
Free expansion, so p ex = 0
So, w = _
p ex _
V = 0
Since, adiabatic process, so q = 0
Since both q and w are equal to zero. Then according to first law of thermodynamics _
E = q + w
_
U = 0
Hence, _
T = 0
