A compressional wave transports energy through matter by causing particles in the medium to bump into each other, passing on the energy from one particle to the next. This results in a chain reaction of vibrations propagating through the medium, carrying the energy with it.

That would be sound.
No, compressional waves require a medium to travel through, so they cannot travel through a vacuum where there is no matter. Sound waves, which are compressional waves, cannot propagate through a vacuum.
A wave in which matter moves in the same direction as the wave is called a longitudinal wave. In a longitudinal wave, the particles of the medium oscillate parallel to the direction of energy transport. Sound waves are a common example of longitudinal waves.
True. Waves transfer energy through a medium but do not cause the physical displacement of matter in the medium itself.
Waves can transport energy without moving matter because they transfer energy through the vibration or oscillation of particles in a medium, such as air or water. This movement creates a ripple effect that carries energy from one point to another without physically displacing the particles themselves.
