All mechanical waves must have a medium through which to propagate. The medium may be an matter in any phase - solid, liquid, gas, etc. The waves propagate in either transversely or longitudinally modes. Transverse propagation is perpendicular to the direction of motion; some examples of transverse waves are things like a flag rippling in the wind or the waves of a ribbon or curtain moving up and down along the surface. Longitudinal waves move parallel to the direction of propagation as compressions and rarefactions (stretching). Some examples of these waves are sound waves, and compression waves in springs. Some waves, like water waves, may show both transverse and longitudinal character.
Mechanical waves need a medium to travel in
Mechanical waves may travel through any medium except vacuum.
No, mechanical or pressure waves can not travel through empty space
Mechanical waves travel fastest in mechanically-most-dense media. Electromagnetic waves travel fastest in optically-least-dense media.
Mechanical waves require a medium to travel, where electromagnetic waves do not.
Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).
Mechanical waves are waves that require a medium in which to travel, i.e., a solid or fluid. As sound needs a medium to travel, sound is a mechanical wave.
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
Mechanical waves require media through which they can travel.

vacuum
Yes, but mechanical waves need matter to travel through. EM waves can travel through vacuums as well.
