• The speed of sound depends on several variables, but the only independent variable we need to.
• Because the speed of transmission depends on molecular collisions, the speed of sound depends on the state of the gas. The speed of sound is a constant within a given gas and the value of the constant depends on the type of gas (air, pure oxygen, carbon dioxide, etc.) and the temperature of the gas

In air at 20°C sound travels at 344 m s−1, in water at 20°C it travels at 1461 m s−1, and in steel at 20°C at 5000 m s−1. The speed of sound in a medium depends on the medium's modulus of elasticity (E) and its density (ρ) according to the relationship c = √(E/ρ) The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 metres per second (1,126 ft/s; 1,236 km/h; 768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s.In common everyday speech, speed of sound refers to the speed of sound waves in air The great question is that since sound is a mechanical wave, its speed is influenced by the medium of propagation and also by the temperature. In most cases, the techniques reported for that goal usually make use of expensive equipment and techniques that may not be affordable and/or easy to implement in schools, which is an experimental limitation for the teachers to show this influence on.

### Nondestructive Evaluation Physics : Soun

The Velocity of sound in sea-water changes with water pressure, temperature, and salinity. It is calculated by the Del Grosso or UNESCO formula. The temperature of sea water is assumed to be 4 degrees C in the depth of 1000m, and 2 degrees in the depth of 3000m or more Sound travels much slower than light—you can observe this while watching a fireworks display (see Figure 14.6 ), since the flash of an explosion is seen before its sound is heard. The relationship between the speed of sound, its frequency, and wavelength is the same as for all waves: v = f λ, v = f λ, 14.1 1976 Standard Atmosphere Calculator. Input.

The deduced second virial coefficient is mainly consistent with the previous measurements, the predictions of an existing equation of state, and the general virial coefficient correlation

### thermodynamics - What is the speed of sound in space

Values of the Speed of Sound: One of the most common questions we receive is fow fast is the speed of sound, and as was pointed out earlier, there is no single value to quote. The speed of sound, also known as Mach 1, changes throughout the atmosphere based on the temperature at any given altitude
