9. Kinetic Molecular Theory (KMT); how theories differ from laws
Student Reading: Ideas in Science: Theories, Hypotheses, and Laws
http://www.visionlearning.com/library/module_viewer.php?mid=177Try the KMT simulator at the PHET site, to see how the experimentally determined relationships between P, V, number of particles, and T which we've determined experimentally, can be used to support a particle theory of matter. We include in this model the understanding that particles have mass, and kinetic energy. We suppose that most of the volume of a gas is the space between particles, not the particles themselves. Particles are in random motion, and exchange energy through elastic collisions.Read chapter 13.1 in your textbook for a more thorough review of kinetic molecular theory.The chemteam.info site includes additional (optional) readings, problem sets and tutorials. Even though these are optional, you may benefit by looking through a few of the sample problems!Ever wonder how a drinking straw works? This entertaining video explains, and may also be useful review (most students have seen this in class).
