How come soundwaves can travel through solid liquid and gases as longitudinal waves?
Answers:
Because sound waves are longitudinal waves. This means that the transference of sound energy is done through vibration of atoms. When the atoms vibrate, they hit other atoms and therefore pass the energy on to the other atoms and this continues as the sound waves 'travel' until the energy is used up.

yeah, what emily k said. and as they need a medium, they cant travel in a vacuum. thats why in space, no one can hear you scream.
Emily_K is almost right except that atoms do not physically hit each other, they only exert disturbances in the electromagnetic forces that keep atoms from merging in whatever the state of the medium they are present in and this electromagnetic 'push' is passed on to their neighbouring atoms.
through vibration of atoms. since in solid, atoms are very dense ,
so it travels faster thru solid than liquid than gas.
Conservation of momentum helps.

Sorry I don't recognise the term Solid Liquid?
I thought there was only Gas Liquid & Solid with a Latent Heat condition at each change?
