Q. 75.0( 1 Vote )
In an adiabatic process, no transfer of heat takes place between system and surroundings. Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following.
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
Reason: As it is an adiabatic process so q=0 and as it is free expansion of gas is there so w=0.
From the first law of Thermodynamics
ΔU = q + w
This means that ΔU will be 0 which indicates that temperature will remain constant.
