The temperature at which the speed of sound in air becomes double of its value at `27^(@)C` is

A

`273^@C`

B

`0^@C`

C

`927^@C`

D

`1027^@C`

Text Solution

Verified by Experts

The correct Answer is:
C
velocity of sound `v prop sqrt(T)`
`therefore v/(2v) = (sqrt(273 + 27))/(sqrt(T)) " or " T = 1200 K = 927^@C`
