WebMar 30, 2024 · speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second. The speed of sound in liquid water at 8 °C (46 °F) is about 1,439 metres (4,721 feet) per second. WebApr 7, 2024 · ρ = Density of fluid. By adiabatic compression and rarefaction, sound waves move through a gas (expansion). The speed of sound in gas formula is given by, γ =. γ × R × T M. γ = Adiabatic index. R = 8.314 J/mol - k universal gas constant. T = Absolute temperature. M = Molecular mass. WebAt 0ºC , the speed of sound is 331 m/s, whereas at 20.0ºC it is 343 m/s, less than a 4% increase. Figure 3 shows a use of the speed of sound by a bat to sense distances. Echoes are also used in medical imaging. Figure 3. A bat uses sound echoes to find its way about and to catch prey. sentence with the word couch
