Why does higher the temperature makes the sound travels faster in the air?

All other things being equal, Its the increased vibration of the air molocules at higher temperature that allows faster transmission of the pressure wave.

Does sound go faster through water or iron?
Sound travels faster in iron. Usually sound travels faster in media with higher density. Also presence of lattice makes difference too.
What is an effect of heat on the temperature of an object?
it makes the particles move faster so it expands.
What is he speed of sound?
The Speed of sound in AIR at 0 degrees C and 1 atmosphere (sea level) is 1190km/h or 331m/s (740mi/h). At higher altitudes the atmospheric pressure is lower, therefore the speed of sound is lower. The speed of sound in a vacuum is ZERO, since the DENSITY of a vacuum is ZERO The DENSITY and ELASTICITY of a medium are the 2 MAIN factors in differences in speed as sound travels through a substance. DENSITY of an object, is the mass/volume, ie kg/cubic meter. ELASTICITY is a property of an object or material which will restore it to its original shape after distortion, or how compressible a substance is (Hardness). A LARGE elasticity value indicates a relative UNcompressable substance. ie RUBBER is less than 0.1, whereas DIAMOND is 1100-1200. seawater is 2.35 In GENERAL terms the higher the density of a substance, the higher the elasticity as well, and the faster sound travels through it. (speed of sound in diamond is >18000m/s [NOT a typo ... 18 kilometers per second]) Temperature also plays a part, but only really in liquids and gasses. (Temperature doesn't effect the crystalline structure of most solids very much, except close to the melting point where covalent bonds start breaking prior to a change of state.) Since higher temperature gasses and liquids have a higher kinetic energy value (they vibrate faster) this makes it easier to transfer shock waves between adjacent particles, thus waves travel FASTER through higher temperature versions of the same medium, even though the density is lower. ie sound travels faster through air or water at 90 deg than the same substance at 20 deg.
Do warm fluids have a lower density or a higher density?
The density of fluids decreases as temperature increases. This is because heat makes the particles in fluids move faster and spread farther apart, which means that there are fewer particles in a given volume.
What makes an object hot or cold?
We perceive an object as hot or cold according to how fast its particles are moving. The faster they move, the hotter the object.

What is relationship between temperature and specific volume in figure?
higher temperature makes the molecule mvoes more faster and speeds further apart.
What does temperature do to particles?
it makes them move faster or vibrate
What makes you jump higher and run faster?
Brandon can jump higher then Will Donovan
If you store tennis balls at a warm temperature will it affect the rebound?
Yes it will effect the rebound height. It tends to bounce higher in a warm temperature because the molecules speed up and strike the inner core more and faster so this makes it bounce higher!
How does adding salt to water effect how it boils?
Raises the temperature at which the water boilsAdding salt does not make the water boil faster, but makes the water boil at a higher temperature than 100 degrees Celsius. This may allow you to cook food in that water faster than in plain boiling water.
How does helium make your voice sound weird?
Helium is 6 times less dense than air which means that it travels through your lungs much faster which makes your voice and your vocal chords sound much higher.
How does temperature effect the rate od dissolving sugar?
it makes it faster to dissolve
Will spagetii cook faster with salt?
Yes, actually the salt makes your water boil at a higher temperature. So instead of your water boiling at 100 degrees Celsius it boils at 110 degrees Celsius. So when you put your noodles in they cook faster. :)
What salt makes water boil faster?
Sea Salt makes water harder (higher boiling point) to boil. The only way to make water boil faster is to get EVERYTHING (all dissolved and undissolved) out of the way of the escaping water molecules and crank up the temperature (give em the "HOT-FOOT!)!
What is an effect of heat on the temperature of an object?
it makes the particles move faster so it expands.
Which makes water evaporate faster water or light?
Temperature and pressure are important factors.
