Question

How to speed of sound increase____

Answer 1

Answer:

The speed is proportional to the square root of the absolute temperature, giving an increase of about 0.6 m/s per degree Celsius.

Answer 2

The speed of sound increases with increase in temperature. But sound is a mechanical wave, and it travels faster when molecules are closer. But an increase in temperature will draw molecules away from each other, and then accordingly the speed of sound should be slower.
