The '''speed of sound''' is {{convert|1235|km|mi|0}} per hour or {{convert|330|m|ft|0}} per second in dry air in [[room temperature]]. It travels at 1500 meters per second through water. Sound moves faster through liquids and solids than air, since they have a larger specific modulus, meaning they are stiffer. 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 [[temperature]]s, for example in the [[stratosphere]].
You can calculate the speed of sound like this:
Line 11 ⟶ 10:
R is the gas constant (<math>287 N*m/kg*K</math> for air)
T is temperature (in Kelvins)

The speed of sound is also known as [[Mach number|Mach]] 1. Things that go faster are [[supersonic]], and things that go five times that speed (Mach 5) are hypersonic.
