As air becomes warmer how does the speed of sound in air change?

∙ 12y ago
If the temperature goes down, the speed of sound goes also down.
Speed of sound in air is c ≈ 331 + 0.6 × T.
T = Temperature in °C.
Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.

Explain how temperature affects 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.
How does increasing the temperature affect the speed of sound in the air?
Speed of sound increases, when temperature increases. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Does sound velocity change based upon sound frequency?
Speed of sound is not frequency dependent. Speed of sound is dependent only on the temperature. At 20°C the speed of sound is 343 m/s.
What happens to the sound an object makes when the speed of vibrations decreases?
When the speed of vibrations decreases, the pitch of the sound produced by the object lowers. This is because the frequency of the vibrations decreases as well. As a result, the sound becomes deeper or lower in tone.
How does temp and humidity change the speed of sound?
Yes, it affects the density of air and thus the speed of sound in air.
What happens to the speed of sound in air if the air becomes warmer?
as air become warmer velocity of sound increases
What is the speed of sound and what does the speed depend upon?
It depends on the medium and the temperature. The warmer and thicker the medium the faster the sound travels.
What can change the speed of sound?
No.

What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
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 increasing the temperature affect the speed of sound in the air?
Speed of sound increases, when temperature increases. Speed of sound in air is c ≈ 331 + 0.6 × T. T = Temperature in °C. Speed of sound in air at 20°C is c ≈ 331 + 0.6 × 20 = 343 m/s.
Does sound travel faster in air in summer or in winter?
Speed of sound is proportional to absolute temperature. It should therefore travel faster in warmer weather.

Does sound velocity change based upon sound frequency?
Speed of sound is not frequency dependent. Speed of sound is dependent only on the temperature. At 20°C the speed of sound is 343 m/s.
What happens to the speed wavelength and frequency when sound wave passes from cool air into warmer air?
the speed and wavelength increase but the frequency stays the same
The peak of sound wave where the lowest air pressure occurs?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
