How Bonding and Structure are Related to the Properties of Substances


  • 1) The three states of matter are solids, liquids, and gases. Materials will move between these three states of matter depending on the amount of energy required to change their state, which is based on their structure and bonding. Use the particle model to outline the differences between the three states of matter. Refer to the arrangements, movement and energy of particles in each state, and how these relate to their properties 6 Marks

  • 2) Give the two limitations of the particle model 2 Marks
