WebIf sound travels through the air at a speed of 344 m/s, what should be the length of a tube closed at one end to have a fundamental frequency of 128 Hz? Strategy The length L can be found by rearranging the equation f n = n v 4 L . Discussion WebAnswer to Question #299697 in Molecular Physics Thermodynamics for Breck. What is the speed of sound (in m/s) in carbon dioxide at the normal boiling temperature of water? v=\sqrt {\frac {\gamma RT}M}=887~\frac ms. v = M γRT = 887 sm.

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 … 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 … 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 … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". For fluids in general, … See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature.
