NEET Physics Question - Thermal Physics

Assertion (A): Air quickly leaking out of a balloon becomes cooler.

Reason (R): The leaking air undergoes adiabatic expansion.

(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:

Air quickly leaking out of a balloon undergoes rapid expansion. This is an adiabatic process where the gas does work, leading to a decrease in internal energy and thus temperature.

Both (A) and (R) are true and (R) is the correct explanation of (A).
