In an adiabatic process, no transfer of heat takes place between system and surroundings.
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.
(i) q = 0, ΔT ≠ 0, w = 0
(ii) q ≠ 0, ΔT = 0, w = 0
(iii) q = 0, ΔT = 0, w = 0
(iv) q = 0, ΔT < 0, w ≠ 0

(iii) q = 0, ΔT = 0, w = 0
Justification : free expansion w = 0 adiabatic process q = 0
ΔU = q + w = 0, this means that internal energy remains constant. Therefore, ΔT = 0.
In expands under adiabatic conditions into a vaccum no heat is absorbed or evolved since no external work is done to separate the molecules.ideal gas there is no intermolecular attraction. Hence when such a gas
Correct option:(c) q = 0, ΔT = 0, w = 0
Explanation:
Justification : free expansion w = 0
adiabatic process q = 0
△U = q + w = 0, this means that internal energy remains constant. Therefore,
△T = 0.
