Does sound travel faster in the air or in water? And why?
Water.
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound.
The pressure wave disturbs the particles in the surrounding medium, and those particles disturb others next to them, and so on.
