They do not move from their positions as they all keep a definite shape and volume (in a fixed position) What structure do particles in a solid have? There are strong forces of attraction between particles in a very regular lattice arrangement. How are the particles in a liquid arranged? They are constantly moving with random motion but they tend to stick together and they do not keep a definite shape but they keep the same volume. What are the forces of attraction like in a liquid? There is some force of attraction between the particles but they're free to move past and alongside each other. How does a high temperature effect particles in a liquid? The hotter the liquid gets, the faster they move- causing the liquid to expand. If the liquid becomes too hot, it will evaporate and become a gas. How does a low temperature effect particles in a liquid? If the temperature gets too cold, the
