Sound is caused by the vibration of a medium (usually air) and it travels in waves. In this KS2 Science quiz we open our ears to hear all about sound! When you hear a sound your ear is picking up a vibration in the air. The energy from the vibration travels in waves – when these waves travel to your ears and then to your brain, you hear the sound.

Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound. Gases: The speed of sound depends upon the properties of the medium it is passing through.

Sound travels best through solids, followed by liquids and then gases. If there is not a state of matter for sound to travel through, there is no sound. Sound velocity is generally larger in solids than it is in liquids. Sound velocity is larger in liquids than in gases, in most instances, because of the elastic constants of.

In reality, sound is passed from molecule to molecule, and it travels through liquids better than gasses, and through solids better than in liquids. This is because the molecules in a solid are closer together and can easily pass the sound wave along.

The reason why the sound velocity is usually larger in solids than in liquids and usually larger in liquids than in gases is because of the elastics constants of the material. What determines the elastic constants of a material is the interatomic bond strength. The stronger the bond, the higher the elastic constants.
