In part one of this DVD, chemistry authorities, including "Helium Man" and two janitors, lay down the law--Boyle's Law, Graham's Law, and Dalton's Law. They also present the Kinetic Molecular Theory and the ideal Gas Equation and elaborate on partial pressures and the difference between diffusion and effusion. Part two investigates kinetic energy; ion-dipole, dipole-dipole, and London disperson forces; hydrogen bonds; phase diagrams; and vapor pressure --cover.
