Speed of sound in mph?

The speed of sound in MPH is 768 at 20C in dry air.


What is the speed of sound in dry air at 20C?

The speed of sound at 70oC is 371.333m/s. Refer to the related link below for a calculator for the speed of sound in air.


How many seconds does it take for sound to arrive at the back of a big auditorium if the temperature in the room is 20C and the stage is 33.6 meters away?

The speed of sound in air at 20C is approximately 343 meters per second. To find the time it takes for sound to travel 33.6 meters, you divide the distance by the speed: 33.6 meters / 343 m/s ≈ 0.098 seconds.


State the speed of sound?

The speed of sound at sea level is 340.29 miles per second.


What is the effect of temperature on the speed of sound?

Speed of sound depends on the density of the medium. As temperature increases density decreases due to expansion in the volume. Hence speed of sound gets affected by the change in temperature. Speed of sound is directly proportional to the square root of the temperature of the medium.


When is the speed of sound near the ground less than the speed of sound higher up?

If the speed of sound near the ground is less than the speed of sound higher then in this special case the temperature at the ground must be less than the temperature higher up. Usually the temperature at the ground is warmer than the temperature high up in the sky. The speed of sound changes mainly with the temperature.


How does the temperature of a material affect the speed of sound passing through it?

Temperature is a fact for speed. Speed is increasing with the temperature.

Does temperature affect the speed of sound?

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.


Why the speed of sound dicrease with rise in temperature?

The question is wrong. With rising temperature the speed of sound is also rising. Air temperature affects the speed of sound. The formula to find the speed of sound in air is as follows: c = 331 m/s + 0.6 m/s * T (°C) c is the speed of sound and T is the temperature of the air. One thing to keep in mind is that this formula finds the average speed of sound for any given temperature. The pitch of woodwind instruments goes up, when the temperature goes up.


What is the average temperature of eartth?

Explain why the speed of sound changes if the temperature of the medium changes?

The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
