Question:
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, ∆T ≠ 0, w = 0
(ii) q ≠ 0, ∆T = 0, w = 0
(iii) q = 0, ∆T = 0, w = 0
(iv) q = 0, ∆T < 0, w ≠ 0
Solution:
Option (iii) q = 0, ∆T = 0, w = 0 is the answer.
