How is sound made why does it travel faster through solid elements and what is its speed?
Sound is a transverse wave made by particles banging into one another. (thus sound cannot travel in a vacuum)
In air (a gas), the particles are a long way apart so it takes longer for them to collide with one another to carry the sound.
In a solid, say a bar of metal, all the particles are jammed really close together, so if you bang one end of the bar, the wave will travel quickly down the length of the bar.
Sound travels at around 330m/s in air, and how fast it goes in solids depends on the properties of the solid, but I think for most metals it is very roughly around 600m/s
Hope this helps.
Sound, which is mechanical energy, travels through a solid by setting up a mechanical compression wave in that solid. When the compression wave of the sound in air strikes the solid, it compresses the solid. It isn't much, but the energy delivered by the air is transferred into the solid. Waves of compression and rarefaction move through the solid as they did in air, but move much faster in a solid.
Sound travels faster in a medium that that has no or less interference. In other words we can say that it will travel faster in solid practically thinking that sound is echoced by the solid objects better than the liquid medium and as a result the sound waves travel with faster velocity and travel greater distance.
