Classify forms of matter as mixtures or substances. 6. Classify substances as elements or compounds 7. Write a description of matter in terms of the kinetic molecular theory. 8. Write a description of the relationship between temperature and motion. 9. Write a description of the similarities and diFerences between solids, liquids, and gases in terms of the kinetic molecular theory. Your description should include mention of the particle nature of matter, the degree of motion of the particles, and the degree of attraction between the particles. 10.
