How Does Temperature Affect the Speed of Sound? - Reference.com

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … See more Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%. The discrepancy is due primarily to neglecting the (then unknown) effect of … See more The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by … See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, the speed of transverse (or shear) waves depends on the shear deformation under shear stress (called the See more General physical considerations The medium in which a sound wave is travelling does not always respond adiabatically, and as a result, the speed of sound can vary … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature.

WebJul 1, 2024 · The speed of sound is affected by the temperature of the air. Hot air makes sound travel faster, while cold air makes it travel further. Other factors, such as humidity and pressure, can also affect the speed of sound. The speed of sound in liquids is faster than in gasses but slower than in solids. The speed of sound in a vacuum is effectively ... WebAug 25, 2009 · 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 °F. (0 °C.), the speed of sound in air is 1,087 feet per second (331 m/s); at 68 °F. (20 °C.), it ...
