. Which of the following is correct option for free expansion of an ideal gas
under adiabatic condition
(a) q = 0,ΔT ≠ 0,w=0
(b) q ≠ 0,ΔT = 0,w=0
(c) q = 0,ΔT = 0,w=0
(d) q = 0,ΔT < 0,w≠0
Best Answer
Correct Option is : (c )
HINTS- FREE EXPANSION (P=0)
ADIABATIC (q=0)
According to first law of thermodynamics
ΔU = Δq + Δw
0+0= 0
Internal energy remain constant
that means ΔT = 0.
(since it was an ideal gas and internal energy and temperature are directly related)
