Question

Why is the speed of sound the lowest in Air?

Answer 1

Explanation:

For a given medium, sound has a slower speed at lower temperatures. You can compare the speed of sound in dry air at different temperatures in the following Table below. At a lower temperature, particles of the medium are moving more slowly, so it takes them longer to transfer the energy of the sound waves.

Answer 2

Answer:

The speed of sound depends upon the properties of the medium it is passing through. ... This is because at lower temperatures, molecules collide more often, giving the sound wave more chances to move around rapidly. At freezing (0º Celcius), sound travels through air at 331 meters per second (about 740 mph).
