So all of the inside particles move in unison, along with the shell. This model explains the properties of substances in their different states, as well as changes of state. For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl, whereas water is always made from twice the number of hydrogen atoms as oxygen atoms, so it is H. An impure substance made from different elements or compounds mixed together that are not chemically joined. This Foundation GCSE BBC Bitesize video is from the original programmes from 2000 that were broadcast on BBC2. The flat section of a temperature - time graph shows the melting or boiling point of a substance, as the energy transferred to the substance when it changes state is called latent heat, where the substance doesn't change temperature. The particles in liquids are arranged in a random way, and are close together, touching many of their neighbours. A single drop of water is made up of more than a billion trillion extremely tiny water molecules. Definition: A biomolecule is a chemical compound found in living organisms.
