How does temperature affect sound waves?
149054
In air, higher temperatures result in faster sound waves.  The formula is \n\nV = Vo SQRT( 1 + T/273) , where V = speed of sound in the air, T = temperature in degrees Celsius, and Vo= speed of sound at 0 degrees Celsius = 331 m/s.

None, sound is a wave not a particle. Sound is just a wave of vibrations travelling through atoms.

Note that it also depends on frequency.\n\nhttp://en.wikipedia.org/wiki/Loudness

The heat causes waves in the air that affect the passage of light becuase the density is different than the surrounding air.  Same happens if you look at the fron of an  air horn like at a football game. But it's the opposite, it's caused by extreme cold.

The speed of sound v in dry air at temperature T (in celsius) is given by:\n\nv = (331.4 + 0.6 T) m/s\n\nSpeed of sound depends on various factors, such as, temperature, humidity, density, etc. of the medium in which it travels.\n \nThe following links provide the speed of sound calculators and related links:

Not on any realistic scale.  The particles in matter move according th the net of all the forces acting on them, including gravity.  Sound is a disturbance to the position of those particles, which propagates as a compression wavefront.  Gravity affects the steady-state behavior of each particle.  Sound just creates a short-term displacement.

Increasing the temperature (adding energy) increases the molecular vibration.

The speed of sound increase at a rate of 0.6-m/s per degree C starting at 0 degrees C with a speed of 330-m/s.  At 30 degrees C the speed of sound will be 330-m/s + (0.6-m/s*30)=348=m/s

Yes, speed of sound is "fixed", like the speed of light and does not depend on the frequency\n\nFrequency affects the volume, if it's peak and trough changes. Higher the peak and trough, the louder the sound and vice versa.\n\nFrequency affects the pitch,if it gets higher or lower. Higher the frequency, higher the pitch, lower the frequency lower the pitch.\n\nHowever sound does change speed depending on the medium it's traveling in.  It travels faster in water,I believe.\nAnd it cannot travel in vacum, so it has zero speed in space.

The temperature of any material is a measure of the average kinetic energy of all the atoms in the material. As you increase this kinetic energy (temperature) then the atoms are more energetic the atoms vibrate with more energy this means each atom takes up more space and so the total volume of the material increases aswell

Sound is a waveform passing through a medium (in this case air). Cooler night air is denser than warm daytime air and therefore easier to travel through and propagate. Other factors already mentioned contribute to it seeming louder, but do not help it to travel further.

sound is particles vibrating in succesion. waves. \nthere are more particles in iron so the sound is trasnfered faster.

The speed of sound in water (including seawater) depends on several factors, but most important is the the temperature of the water.  By measuring the time it takes for an acoustic signal to travel from a source to a receiver, one can determine the average temperature along the path followed by that sound signal. (Other factors that include sound velocity or travel time include salinity, pressure (i.e. pressure-induced changes in density), and ocean currents.)  By measuring the average temperature along many different paths, one can reconstruct a 3-dimensional "map" of the temperature distribution in the oceans.  \n\nBy following the changes in temperature over time, one can detect long-term changes in the temperature distribution and hence average temperatures of the oceans.

You have it backward.  The temperature is dependent on some function of time not the other way around.

Sound travels at different speeds depending on what it is traveling through. Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound. \nGases: \n\nThe speed of sound depends upon the properties of the medium it is passing through. When we look at the properties of a gas, we see that only when molecules collide with each other can the condensations and rarefactions of a sound wave move about. So, it makes sense that the speed of sound has the same order of magnitude as the average molecular speed between collisions. In a gas, it is particularly important to know the temperature. This is because at lower temperatures, molecules collide more often, giving the sound wave more chances to move around rapidly. At freezing (0º Celcius), sound travels through air at 331 meters per second (about 740 mph). But, at 20ºC, room temperature, sound travels at 343 meters per second (767 mph). \n\nLiquids: \n\nSound travels faster in liquids than in gases because molecules are more tightly packed. In fresh water, sound waves travel at 1,482 meters per second (about 3,315 mph). That's well over 4 times faster than in air! Several ocean-dwelling animals rely upon sound waves to communicate with other animals and to locate food and obstacles. The reason that they are able to effectively use this method of communication over long distances is that sound travels so much faster in water.\n\nSolids: \n\nSound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids are not faster than in all liquids

Sound is the effect your brain evokes when your tympan vibrates. These vibrations are usually caused by air that was set on the move by a distant body (like a bell, for instance). Water and other liquids can perform the same effect as air, although the "sound" you will perceive is quite different due to the distinct elastic properties of the liquid.\nIn outer space, there is almost no matter at all (that´s why its called a "vacuum"). So, there is no way of propagating a "wave" since waves need matter to be propagated (air, water, solids, etc). \nThat´s why sound doesn´t exist in outer space.

Mass is not affected by temperature, but volume can be slightly changed because if an object heats up, the particles begin to move faster and so it expands, or vice versa if the object gets cooler.
