Further Education: Note: In chapter 5, students will learn that water molecules and coloring molecules are attracted to each other. They vibrate in their fixed positions, not changing shape, so they are the least energetic of the states of matter. The energy required by different materials depends on their 'heat capacity' and 'latent heat'. An overview of the definitions of different types of chemicals, how chemicals can be represented in chemical equations, how chemicals can be separated, and a number of important calculations related to chemical formulae.
