Matter is made up of atoms and molecules, which may only be seen by electronic microscope. Kinetic Molecular Theory of Matter: The kinetic molecular theory explains the forces between molecules and the energy that they possess. This theory has 3 basic assumptions. 1. Matter is made up of tiny small particles (atoms, molecules or ions).

SOUND INSULATION - INVESTIGATING WHICH MATERIALS …

Sound is a vibration – it needs something to pass on these vibrations (unlike light which can pass through a vacuum). Some materials allow sound pass through them very easily, especially hard rigid ones like metals. Other materials, especially soft ones like cotton wool, absorb sound. Ears are delicate and need to be looked after.
