How is sound propagated through a material medium ? What is wave motion ?

The sound wave propagates through

Sound can propagate through _________ medium.

Wave motion is a propagatlon of energy through a material medium due to repeated periodic motion.Transverse waves cannot be propagated through gases. Why?

With the propagation of a longitudinal wave through a material medium, the quantities transmitted in the propagation direction are
