Question

answer plzzzzzzzzzzzzzzzzat what temperature the velocity of sound in air is two times its velocity at 20 degree centigrade

Answer 1

Answer:

The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.

Sound pressure: p, SPL,LPA

Sound intensity: I, SIL

At which temperature the speed of sound 331.3 m/s (velocity of sound) will be doubled? A temperature of 819.45°C will double the speed of sound to 662.6 m/s.
