How does temperature affect the speed of a sound?

Answer 1

If the temperature rises, the woodwinds and the brass rises in the pitch, because of changing of the speed of sound. If the temperature rises all string instruments and the piano fall in pitch. Lower the temperature , faster is the speed of sound because at lower temperature molecules collide more often, giving the sound wave more chances to move around rapidly.

Answer 2

Friction causes temp. which is a force that opposes motion. That is why it effects speed and motion.

The speed of sound increases with the density of the medium through which it is passing.

Temperature affects the speed of sound by affecting the density in different ways. The main way is that the amount of water vapour that air can hold depends on the temperature. The higher the temperature the more water a given volume of air can hold. (This is why you get dew as the cold air can no longer hold on to the moisture.) High humidity increases the densityof air and so increases the speed of sound.

The temperature also affects the density directly - through expansion. That will tend to reduce the density and so reduce the speed of sound. This effect is usually less significant.

Answer 3

It increases during low temperatures and decreases in high temperatures. Molecules are closer together when they are colder so they vibrate against each other immediately. in warm temperatures, the are farther apart, making vibrating against each other. thus, reducing the freuqency

==========================================

A fascinating and uniquely graphic explanation !

Completely wrong, but fascinating and graphic nonetheless.

Temperature affects the wavelength of sound waves, but has

no effect on the frequency.

==========================================

Isn't affected wavelength the same thing as affected frequency?

Did you mean amplitude by any chance?

Answer 4

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.

Answer 5

The speed of sound has much to do with the temperature. At 20°C the speed of sound is 343 m/s. If the temperature decreases also the speed of sound decreases.

Answer 6

Temperature will affect the strength of air particle interactions (an elastic property).

The lower the temperature, the easier it is for the sound to travel through the air.

Answer 7

No, but the question the other way round is correct: Does temperature has an effect on sound? Yes.

Answer 8

If the temperature goes up, the pitch of woodwind instruments go up too, but the pitch of string instruments go down.
