Assertion : Sound would travel faster on...

Assertion : Sound would travel faster on a not summer day than on a cold winter day,
Reason : Velocity of sound is directly proportional to the square of its aboslute temperature.

A

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

B

If both 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:
C
The velocity of sound in a gas is directly proportional to the square root of its absolute temperature `v = sqrt(( gamma RT)/( rho V) )`. Since temperature of a hot day is more than cold winter day, therefore sound would travel faster on a hot summer day than on a cold winter day.
