Elements of Chemistry: Gases, Liquids, and Solids DVD
Practically all elements and substances can exist as a gas, a liquid and a solid, but they still retain their original chemical composition. The Kinetic-Molecular Theory explains the behavior of different states of matter by examining the forces between the particles and the energy they possess. Temperature is the primary variable that determines the state of an element or a substance but pressure can also have an influence. This program reviews the different gas laws as well as examining the characteristics of substances and elements when they are liquids and solids.
