Speed of sound in air is c ≈ 331 + 0.6 × T.
T = Temperature in °C.
Speed of sound in air at 0°C is c ≈ 331 + 0.6 × 0 = 331 m/s.
0,72 Mach is a subsonic speed. Mach number = speed of an object/speed of sound The speed of sound in dry air at 20 0C is 1 236 km/h.
Yes. The equation relating temperature (in degrees Celcius) to the speed of sound is v=331+0.60T. This means that when the temperature is 0C (the same as 32F), the speed of sound will be 331m/s.
Mach is a non standard unit based on the speed of sound through the medium, Mach 1 is the speed of sound, and 0.92 Mach is 92% the speed of sound which is approximately 313.0668 m / s or 1127.04048 km/h or 700.310487 mph.
Sorry, the atmospheric pressure has really nothing to do with the speed of sound at 0c, but he temperature is very important Scroll down to related links and read the short article "Speed of sound - temperature matters, not air pressure". The air pressure and the air density are proportional to each other at the same temperature.
Speed of sound c in air at the temperature 0f 20 degrees Celsius or 68 degrees Fahrenheit is 343 meters per second. Scroll down to related links and look at "Speed of sound - temperature matters, not air pressure".
Speed of sound (M/Sec): Sea water at 0C: 1450 Sea water at 20C: 1522 Sea water at 30C: 1545 Butyl rubber/carbon (100/40): 1600 Neoprene: 1510 Neoprene/carbon (100/60): 1690 Rubber (natural): 1600 So, on the whole, sound is slightly faster in rubber
By heating sulfur is melted at 115,21 0C and boiled at 444,6 0C. Sulfur is burned at high temperature in an air atmosphere.
An estimated value is 827 0C.
A proposed (not experimentally determined) value is 1 627 0C.
The equal volume of air that is twice as hot would have a temperature of 20C. Temperature is directly proportional to the average kinetic energy of the air molecules, so doubling the temperature would double the kinetic energy of the molecules.
Where air planes fly, the temperature is below freezing.
Probably snow.
