Detailed Solution

The speed of sound is the distance travelled by sound waves in a given amount of time.

The speed of sound, which is 343 metres per second, is measured under specific conditions, specifically in dry air. The temperature, humidity, and consistency of the air all affect sound speeds.For a given r, sound travels slower at lower temperatures. Because the particles in the medium move more slowly at lower temperatures, it takes longer for the s waves' energy to be transferred.

For every 1 degree that the temperature drops, the speed of sound drops by 0.6 metres per second.

The speed of sound is around 331.5 metres per second at 0 degrees Celsius. As a result, Option 2 is correct.

The speed of sound increases by 0.6 metres per second for every degree Celsius increase in temperature.
