  Hey tom0901,
  
  Sound travels at around 343 metres per second through air, but its exact speed depends on the air it’s travelling through. Warmer air will make it travel a bit faster. Also wetter air will make it travel faster.
  
  It travels by vibrating molecules relative to one another. The stiffness of the molecules connections affects how fast the sound travels. So it travels much faster in liquids than it does through air and even faster again through solids.
  
  It always travels slower than light though, so you see the flash of lightening before you hear the thunder. Knowing the speed that sound travels you can time the difference between the lightening and thunder and guess how far away the storm is!
