Q13 of 118 Page 352

At what temperature will the speed of sound be double of its value at 0°C?

Let the speed of sound be at temperature ,
where

Let be the temperature at which the speed of sound () will be double its value at .



As per the question,
= 2.




∴





To convert Kelvin into degree Celsius:



Hence, the temperature () will be
