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. It depends strongly on temperature as well as the medium through which a sound wave is propagating.

How do you find speed of sound with temperature?
If the temperature is T C = 20 °C (T = 293 K), the speed of sound is v = 343 m/s . The equation for the speed of sound in air v = √γRTM can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331m/s√T273K. v=fλ.
What is the speed of sound in air at 150 C?
At a temperature of 819.45, we get a speed of sound of 662.6 m/s .
How does temperature affect the speed of sound in air?
Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. ... This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. The speed of sound is also affected by other factors such as humidity and air pressure.
How can speed be calculated?
Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time.
How fast does sound travel in a vacuum?
A: 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 through the vibration of particles in a medium, such as water or air. Since a vacuum is empty space, there is no medium for the sound to travel through.
How fast is the speed of sound underwater?
Sound travels about 1500 meters per second in seawater. Sound travels much more slowly in air, at about 340 meters per second. The speed of sound in seawater is not a constant value.
What is the speed of sound at 35 C?
What is the speed of sound at 35°C? ( 352 m/s )What is | Chegg.com.
Which kind of waves are sound vibrations made of?
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below.
Is sound is a longitudinal wave?
Sound waves in air and fluids are longitudinal waves , because the particles that transport the sound vibrate parallel to the direction of the sound wave's travel.
Where does sound travel the fastest?
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
Does speed of sound depend on pressure?
Pressure- At a constant temperature, the speed of sound does not depend on the pressure . Thus an increase in the temperature of the medium increases the speed of the sound.
What is the speed of sound wave?
Speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second .
