Let's see how sound works in everyday life say you are throwing a pool party with all your friends. If you shout underwater, your friend in the pool will hear you faster than your friend on the pool deck because water is a better medium than air.

1. density - heavy materials like metal or rocks carry sound faster than light materials like air

2. Temperature - sound moves faster in warm air than it does in cold air

3. Elasticity - elastic materials like a rubber band let particles move faster

How do particle arrangements affect sound?

Each medium is made of tiny little particles Here is how it works.

In Air - the particles are the most spread out so sound moves slow

In water - particles are closer so they move faster

In solids, the particles are the closest together, moving the fastest.

A Medium is what sound travels through. There are three different types of mediums air water, and solids

Sound is the type of energy that we hear. It is made by vibrations like when you sing or clap your hands. These vibrations are called sound waves and they travel through the air and enter our ears.
