The Total solution for NCERT class 6-12
For the process to occurunder adiabatic conditions, the correct condition is:
(i) ΔT = 0
(ii) Δp = 0
(iii) q = 0
(iv) w = 0
A system is said to be under adiabaticconditions if there is no exchange of heat between the system and itssurroundings. Hence, under adiabatic conditions, q = 0.
Therefore,alternative (iii) is correct.
