how does the temperature affect the speed of sound in air
The speed of sound in a material, particularly in a gas or liquid, varies with temperature because a change in temperature affects the material's density. In air, for example, the speed of sound increases with an increase in temperature.At 32 Â°F. (0 Â°C.), the speed of sound in air is 1,087 feet per second (331 m/s); at 68 Â°F. (20 Â°C.), it is 1,127 feet per second (343 m/s).The terms subsonic and supersonic refer to the speed of an object, such as an airplane, in relation to the speed of sound in the surrounding air.he speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
