Sound waves, like all other waves, are transmitted through a medium by having the particles in the medium actually collide with each other, transmitting the vibration even further. The speed of the wave is proportional to the number of collisions, so the more collisions that can be made the faster the wave can travel. Solids by definition have the closest packed particles, so there can be more collisions in this phase, meaning that solids also have the fastest sound waves. Likewise, gasses have the most spread out particles, so their infrequent collisions mean that gasses have the slowest sound waves. Liquids are halfway between solids and gasses in terms of particle packing, so their speed is in between.
For example, sound travels at around 343 m/s in the air, 1,484 m/s in water, and 5,120 m/s in solid iron!
sound cannot travel through a vacum

Yes
sound will travel through air (gas), the slowest. Because the molecule sin the air are farther apart. Actually rubber it will travel through rubber the slowest. Air is second slowest then water and then granite was all I learned . Also Saltwater is faster then water becaus e there more salt so air goes through it faster.

Yes
Air.
Sound waves don't just travel the slowest in a vacuum, they don't travel at all. The reason is that sound waves, like all mechanical waves, need a medium to travel through.

Well sound would travel the slowest - i.e not at all - in a vacuum. However, for simplistic terms, rubber is actually the slowest that sound will travel through of common objects. I don't know but something like sodium at 3K might be a lot slower.
Sound travels slower through less dense matter because sound is the result of molecules hitting each other. When there are fewer molecules for the vibrating molecules to bump into, sound travels slower.
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
Sound cannot travel through a vacuum, such as in outer space. "Sound" refers to waves of compression which travel through matter. When there is no matter, there can be no such waves, and therefore no sound.
