Sound is about (1) a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. It is an example of a (2) mechanical wave. Sound being known also as a mechanical wave needs matter in order to travel. This matter is better known as (3) medium. Sound can travel in (4) solids (5) liquids and (6) gases. But it cannot travel in a (7) vacuum. Sound move (8) quickly in solid and (9) slowly in gas. There are three factors that affect the speed of sound namely; (1) atmospheric pressure, (2) relative humidity, and (3) atmospheric temperature.
