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

A

`54^(@) C`

B

`327^(@) C`

C

`927^(@) C`

D

`-123 ^(@) C`

Text Solution

Verified by Experts

The correct Answer is:
C
`(v_(2))/(v_(1)) = sqrt((273 + t_(2))/(273 + t_(1))) implies (2)^(2) = (273 + t_(2))/(273 + 27) implies t_(2) = 927^(@) C`
