The ratio of the speed of sound to the average speed of an air molecule at 300 K and 1 atmospheric pressure is close to–

A

1

B

`sqrt(300)`

C

`sqrt(1/(300))`

D

300

Text Solution

Verified by Experts

The correct Answer is:
A
`sqrt(((gammaRT)/(m))/((8RT)/(pi m)))=sqrt(7/5 (pi)/(8) ) =0.73 implies` So, closest answer is 1.
