Question

The temperature at which the speed of sound in air becomes double of its value at $0 ℃$ is

273 K
546 K
1092 K
0 K

The correct answer is: 1092 K

$v proportional to square root of T rightwards double arrow square root of fraction numerator T subscript 2 end subscript over denominator T subscript 1 end subscript end fraction end root equals fraction numerator v subscript 2 end subscript over denominator v subscript 1 end subscript end fraction rightwards double arrow T subscript 2 end subscript equals T subscript 1 end subscript open parentheses fraction numerator v subscript 2 end subscript over denominator v subscript 1 end subscript end fraction close parentheses to the power of 2 end exponent$
$rightwards double arrow T subscript 2 end subscript equals 273 cross times 4 equals 1092 K$
