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

A

`1092^@C`

B

`819^@C`

C

`819K`

D

`346^@C`

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity `prop sqrt("Temperature")`
`(2V)/(V) = sqrt((T_2)/(T_1))`
`T_2 = 4T_1`
`T_2 = 4 xx 273 = 1092 K`
or `T_2 = 1092 - 273 = 819^@C`
