Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.

∙ 14y agoThe speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.5 feet per second. Why? That' physics and nature. Notice: The speed of sound changes with temperature and
a little bit with humidity − but not with air pressure (atmospheric pressure).
The words "sound pressure at sea level" are incorrect and misleading.
The temperature indication, however, is absolutely necessary.

∙ 13y agoSound is a means to transfer energy. How the energy is transferred is through transferring kinetic energy of one element in the medium to the next adjacent element in the medium. The kinetic energy of course makes the element using the energy to move.
Heating up a medium also adds energy to the medium, just as adding sound to it does too. However, adding energy through heating affects the medium by causing the elements in the medium to increase in their kinetic energy and increase the distance of each element to another element. this is because all the elements would be moving around a lot more. Sound energy will then take longer to transfer from one element in the medium to another element.

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.
Why the speed of light has been quoted as being 'in a vacuum' yet the speed of sound is at a specific temperature?
Light will be transported without a medium. The speed of light is = 299 792 458 m/s. Sound need a medium to be transported. It's mostly air, where the temperature is important. The speed of air is 343 m/s at 20 degrees Celsius and 331.3 m/s at 0 degrees Celsius.
What temperature does sound travel faster in?
That depends on the nature of the medium through which it is traveling and how that medium's density is affected (if it is affected at all) by its change in temperature. The denser the medium, the faster sound travels through it. For example, in a sealed chamber containing a gas, the speed of sound is not affected by temperature unless it gets cold enough for the gas to condense to a liquid. As long as it remains a gas, changes in temparature only affect its pressure, not its density.
At which temperature in water does sound travel the fastest?
Sound travels faster as temperature increases, so there is no limit. There is an equation to determine the speed of sound at a given temperature.
What happens to the speed of a wave of the medium temperature and pressure do not change?
remains constant
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.
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.
Why does speed of sound depend on the temperature of a medium through which sound waves travel?
Speed of sound increases with the increase in temperature of the medium .In fact the speed of sound is directly proportional to the square root of absolute temp. of the medium.
Why does the speed of sound depend on air tempersture?
The speed of sound through a medium depends on the density of the medium and the density of air is affected by temperature.
When the temperature of a medium increases the speed of sound decreases true or false?
No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.
Why does the speed of sound change if the temperature of the medium change?
because the density of the medium changes with temprature
As the temperature of a medium increases the rate of speed of sound through the medium what?
The speed of sound through the medium also increases.
In general how does changing the temperature of a medium affect the speed of sound through that medium?
As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in air: V = 331 + 0.59T where T is the air temperature in degrees C.
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.
The speed of a sound wave depend on what?
The medium in which it travels through
What factors affect the speed of sound in a medium?
Temperature, coefficient of restitution, density are some of the factors that affect the speed of sound in a medium.
Which is true about speed of sound in air?
Well speed of sound in air at room temperature is 350 m/s . It depends on the density of the medium. Sound cannot propagate through vacuum. Speed of sound is directly proportional to the temperature of the medium.
