Summary
Explores the phases of matter-solids, liquids, and gases-and how particles in a given phase interact with each other. Phase diagrams explain at what temperature and pressure a given substance will be in a solid, liquid, or gas phase. Practical problems, like how to safely store enough hydrogen gas to power an automobile, are solved by understanding the different behaviors of solids, liquids, and gases.

Summary
Many chemical reactions involve explosions, bubbling gases, flames, and smoke because energy is being transferred from one form to another-the realm of thermodynamics. Thermodynamics, the rules for predicting the progress of a reaction and harnessing the energy released, is key to solving engineering problems, such as making cleaner and more efficient automobile engines.

Summary
Metals allow the transfer of electrons through a process called oxidation-reduction, or "redox," when one species gains electrons while another loses them. Chemists use electron transfers to power the batteries in our flashlights, phones, or cars. In biochemistry trace metals, such as cobalt in Vitamin B12, often drive essential chemical reactions for human health. Redox reactions also occur without metals, as in lightening hair color.
