    • The particle model and density - OCR Gateway

      Matter is made up of atoms about 0.1 nm in size. Atoms and molecules are arranged differently in solids, liquids and gases. Density is calculated from mass divided by volume.

    • Energy, temperature and change of state - OCR Gateway

      Changes in temperature or physical state are caused by transfers of energy. Specific heat capacity determines the energy needed to change temperature, and specific latent heat is the energy needed to change state.

    • Gases - OCR Gateway

      Gases and liquids exert pressure on objects and the walls of their containers due to collisions. The greater the force and frequency of these collisions, the greater the pressure.
