What happens to the speed of sound as the temperature of the air increases?
It increases, because the air molecules move faster
Sound travels through air by the collision and vibration of air molecules that pass the disturbance from one particle to the next.
When the temperature of the air rises, the average kinetic energy of the molecules increases and they move faster, transmitting the vibrations more quickly.
As a result, the speed of sound in air increases with temperature, rising by roughly 0.61 m/s for every 1°C rise.
Hence, the speed of sound increases because the air molecules move faster.
