WebAQA GCSE Chemistry (Combined Science) Unit 2: Bonding, Structure and Properties of Matter The three states of matter are solid, liquid and gas. For a substance to change from one state to another, energy must be transferred. The particles gain energy. This results in the breaking of some of the attractive forces between particles during melting. WebGCSE Chemistry – Silicon Dioxide, Diamond & Graphite. Silicon Dioxide has a high melting and boiling point. The many covalent bonds in silica are very strong, therefore a large amount of energy is needed to break them therefore a high temperature is required. Silica is naturally found as sand. The majority of the sand on beaches is made up of ...
