What happens to the velocity of a sound wave in air if the temperature of the air increases

As sound travels because of collision of air particles vibrating randomly, increasing temperature of air increases the rate of this collision hence increasing the speed of sound travelling through the air.

another example of kinetic energy would be,

kinetic energy   >     moving energy
