Assertion (A): In adiabatic compression, the temperature of system gets decreased.
Reason (R): Adiabatic compression is a slow process.
(1) Both (A) & (R) are true and the (R) is the correct explanation of the (A)
(2) Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(3) (A) is true but (R) is false
(4) Both (A) and (R) are false
Solution:
In adiabatic compression, work is done on the gas \(W =0\), leading to an increase in temperature. Thus (A) is false. Adiabatic processes are typically rapid to prevent heat exchange. Thus (R) is false. Both (A) and (R) are false.
