1.1: understand the three states of matter in terms of arrangement, movement and energy of the particles. close together in regular arrangement close together in free arrangement small amount of kinetic energy moderate amount of kinetic energy. 1.2: understand the interconversions between the three states of matter in terms of: the names of the interconversions, how they are. achieved, the changes in arrangement, movement and energy of the particles. diagram showing the interconversions between the states of matter. particles gain kinetic energy and vibrates faster, allowing particles to overcome the forces of attraction that hold them together in the regular pattern is broken down and particles can now slide past one another particles lose kinetic energy and allows the forces of attraction between the particles to hold them together particles arrange themselves into a regular pattern and are no longer able to slide past one another particles gain kinetic energy and move further apart causing the forces of attraction between the particles to be completely broken and particles lose kinetic energy and vibrates faster, allowing the forces of attraction between the particles closer together this causes the forces of attraction between the particles to be completely broken and are able to escape from the solid. 1.3: understand how the results of experiments involving the dilution of coloured solutions and diffusion of gases can be explained. diagram showing a crystal of potas*ium manganate (vii) dissolving in water add a crystal of potas*ium manganate (vii) and record observations when potas*ium manganate (vii) crystals are dissolved in water, a purple solution forms this occurs as both water and potas*ium manganate (vii) particles are moving freely, sliding over each other, allowing them to mix to form a this is because the potas*ium manganate (vii) particles are less concentrated so the final colour will be weaker allow time for diffusion to take place and record observations
