Assertion : Under given conditions of pressure and temperature, sound travels faster in a monoatomic gas than in diatomic gas.
Reason : Opposition for wave to travel is more in a monoatomic gas than in diatomic gas.

A

If both assertion and reason are true and reason is the correct expleanation of assertion.

B

If both assertion and reason are true and reason is not the correct expleanation of assertion.

C

If assertion is true but reason is false.

D

If assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Velocity of sound in a gas `v=sqrt((gammaP)/(rho))`. For monoatomic gas `gamma=1.67`, for diatomic `gamma=1.40`. Therefore `v` is larger in case of monoatomic gas compared to its values in diatomic gas.
