P6 - Molecules and matter
Independent learning
Introduction
In solids, liquids and gases, the particles are arranged differently. Changes in a material's temperature or state of matter are caused by changes to the internal energy. The energy required by different materials depends on their 'heat capacity' and 'latent heat'. Gases take up more space than solids or liquids and their particles are moving much faster. The temperature, pressure and volume of gases are all related.
