Speed_of_sound

The speed of sound is 1,235 kilometres (767 mi) per hour or 330 metres (1,083 ft) per second in dry air in room temperature. Sound moves faster through liquids and solids than air, since liquids and solids can be pushed together more. Sound cannot travel through a vacuum, which is a space without any air or matter. The speed of sound is affected by temperature. It travels slower at low temperatures.

You can calculate the speed of sound like this:

a = \sqrt{\gamma*R*T} view more...
