Sound is a vibration that travels through an elastic medium as a wave. The Velocity of Sound describes how much distance such a wave travels in a given amount

In Dry Air with a temperature of 21 C (70 F) the Speed of Sound is 344 m/s (1230 km/h, or 770 mph, or 1130 ft/s). Although it is commonly used to refer specifically to air, the speed of sound can be measured in virtually any substance. The Velocity of Sound in liquids and non-porous solids is much higher than that in air.

In the Earth's atmosphere the most important factor affecting the Velocity of Sound is the temperature
