WebR = 8.31 J mol · K. If the temperature is T C = 20°C(T = 293K), T C = 20 ° C ( T = 293 K), the speed of sound is v =343m/s. v = 343 m/s. The equation for the speed of sound in air v =√γRT M v = γ R T M can be simplified … WebMar 13, 2013 · The atmospheric pressure does not affect the speed of sound in air.Temperature does have an effect.Speed of sound in air is c ≈ 331 + 0.6 × T.T = Temperature in °C.Speed of sound in ...

14.1 Speed of Sound, Frequency, and Wavelength - OpenStax
WebIn the U.S. While sound moves at a much faster speed in the water than in air, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.While pressure continues to increase as … WebAccording to the MTU webpage Speed of Sound in Air, some things to consider: if the ideal gas model is a good model for a real gas, ... Compositional changes (mainly water vapour) and especially air … 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 springs. In real material terms, the spheres represent the material's molecules and the springs represent the See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, … See more Speed of sound in ideal gases and air For an ideal gas, K (the bulk modulus in equations above, equivalent to C, the coefficient of stiffness in solids) is given by $${\displaystyle K=\gamma \cdot p.}$$ Thus, from the Newton–Laplace equation above, the speed of … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". For fluids in general, the speed of sound c is given by the Newton–Laplace equation: See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature. For a given ideal gas with constant heat capacity and composition, the speed of sound is dependent solely upon temperature; see § Details below. In such an ideal case, … 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 with frequency.
