Sound will travel a little bit faster in humid air (about 0.1% to 0.6% faster) than it does in dry air. Follow along and we'll see why. Air is mostly nitrogen and oxygen. Nitrogen and oxygen travel around with "buddy" atoms - they are diatomic molecules - they are N2 and O2. Humid air contains water molecules, little H2O molecules. The H2O molecules are lighter than are the N2 and O2 molecules they will displace in air. And "lighter" gases carry sound faster than "heavier" gases. Helium will transmit sound faster than "regular air" will. (The rule of thumb is that low molecular weight gases transmit sound faster than higher molecular weight gases.) That's it in a nutshell. Wikipedia has an article on the speed of sound where this and other questions similar to it are answered. Read that article and you'll be 0.6% to 0.7% smarter. (Possibly.) You need a link, and because this is WikiAnswers, we got one for you.

Do sound waves travel faster in dry air or in humid air?
Sound waves travel faster in humid air because humidity would decrease the density of the air. As density decreases then speed of sound would increase as speed is given as c = ./ P/d ./ is the square root symbol. d is the density and P the pressure. Pressure change wont change the speed of sound since P/d remains constant.
Would sound travel faster in warm air or cold air why?
The sound travel faster in warm air because the average mean speed of the molecules of air is faster in warm air than on cool air. Sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air is greater.
Does sound travel faster in warm or cold air and why?
sound travel faster in cold air half i give you further other person will give
Does sound travel faster in outer space or in air?
sound travels faster through a solid because the particles are right next to each other and so it is faster to vibrate whereas air particles are further apart and take longer to travel. So yes it would travel through the ground faster than air.
Does sound travel faster or slower when the air gets warmer?
faster

Does sound travel faster through different gases?
I learned the other day, in Physics that sound travels faster through warm, dense, humid air, then cold, dry, less dense air. I don't know why though.
What type of air does sound travel faster in?
Sound travels faster in moist air
Does sound travel faster in the air or water?
Sound travels faster in water thanin air.

Will sound travel faster in solid or air?
Much faster in a solid
Does sound travel faster or slower when the air gets warmer?
faster
Does sound travel faster in cold air or in steel?
Sound travels faster in steel than in air, regardless of temperature.
Does sound travel faster therw a desk air?
No.
Does sound travel faster in water air milk or steel?
