Assertion : Change in pressure at constant temperature causes change in the speed of sound.
Reason : Speed of sound in air is directly proportional to square of pressure.

A

Assertin and reason both are correct and reason is the correct explantion of assertion.

B

Assertion and reason both area correct but reason is not the correct explanation of assertion.

C

Asserton is true but reaosn is false.

D

Both, assertion and reaosn are false.

Text Solution

Verified by Experts

Speed of sound in air, `v = sqrt (( gamma P )/(rho )) = sqrt ((gamma P Y)/( M ))`
`= sqrt (( gamma mu RT)/( mu M _(0)))= sqrt((gamma RT)/( M _(0)))=` constant
`(M _(0)=` molecular weight, `mu = no.` of moles)
Speed of sound is not affected by change in pressure at constant temperature.
