Question:
For the process to occur under adiabatic conditions, the correct condition is:
(i) $\Delta T=0$
(ii) $\Delta p=0$
(iii) $q=0$
(iv) $w=0$
Solution:
A system is said to be under adiabatic conditions if there is no exchange of heat between the system and its surroundings. Hence, under adiabatic conditions, q = 0.
Therefore, alternative (iii) is correct.
