Assertion: Air quickly leaking out of a ...

Assertion: Air quickly leaking out of a balloon becomes coolers.
Reason: The leaking air undergoes adiabatic expansion.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If the assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
A
The leaking air of balloon undergoes adiabatic expansion . In this expansion , due to work done against external pressure, the internal energy of air reduces. Thus, it becomes cooler. Adiabatic expansion produces cooling.
