The temperature at which the velocity of sound in air becomes double its velocity at `0^(@)C` is

A

`435^(@)C`

B

`694^(@)C`

C

`781^(@)C`

D

`819^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
D
`V=sqrt((gammaRT)/(M))impliesV alpha sqrt(T)implies(V)/(2V)=sqrt((0+273)/(t+273))impliest=819^(@)C`
