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 s...
At 200°C this relationship gives 453 m/s while the more accurate formula gives
436 m/s. This sound speed does not apply to gases other than air, for example ...
Speed of Sound. Rubber. 60 m/s. Air at 40<sup>o</sup>C. 355 m/s. Air at 20 <sup>o</sup>C. 343 m/s.
Lead. 1210 m/s. Gold. 3240 m/s. Glass. 4540 m/s. Copper. 4600 m/s. Aluminum.
In SI units with dry air at 20°C (68°F), the speed of sound c is 343 meters per
second (m/s). This also equates to 1235 km/h, 1125 feet per second (ft/s or fps),
Oct 17, 2012 ... The official fastest free fall speed was reported as 373 m/s. AH HA! That is just
barely over the speed of sound at 340 m/s. My physics textbook ...

Jan 8, 2015 ... The speed of sound in a vacuum is zero meters per second, as sound cannot
travel in a vacuum. Sound is a wave, which means it spreads ...
"Sound waves move through air at sea level at a velocity of 343 m/s at room
temperature (20 °C). ... "The speed of sound in air is 331.5 m/s at 0 °C." 331.5 m/s
The ideal gas model predicts that the speed of sound in a pure gas will be ... the
average molecule is moving at about 500 m/s (close to 1000 miles per hour).
