The speed of sound in air is _________ temperature?

Sound waves require a medium in order to travel. A medium can be a solid, liquid, or a gas such as air. The speed of sound depends on both the elasticity and density of the medium. When the elasticity increases and density decreases of a medium, sound is allowed to travel faster.
Temperature affects the speed of sound by changing the density of the medium in which a sound wave travels. In most cases, when the temperature of a medium increases so does the speed of sound through that medium. Higher temperatures lower the density of a medium, which puts less resistance on the sound waves. 
The speed of sound increases by 0.6 meters per second for every degree-Celsius increase in temperature..
