TERMINOLOGY Kinetic energy Potential energy Sublimation Deposition The phase change in which a substance changes from a solid to a gas vapor without changing to a liquid first. The energy a substance must absorb in order to change from a liquid to a gas. Energy an object has due to its motion. The phase change when a gas or water vapor changes directly into a solid without first changing into a liquid. The energy a substance must absorb in order to change from a solid to a liquid. Energy that is stored as a result of position or shape. Kinetic energy Potential energy Sublimation Deposition Vapor pressure Heat of fusion Heat of vaporization

Review What are the five states of matter? How can materials be classified? Describe the states of matter for solid, liquid, and gas. What is kinetic energy? State the kinetic theory? Explain and illustrate the behavior of solids, liquids, and gases.

Review Answers Solid, liquid, gas, plasma, & Bose-Einstein Condensate Materials can be classified as solids, liquids, or gases based on whether their shapes and volumes are definite or variable. Solids have def. shape and def. volume, liquids have def. vol. and no def. shape, and gas has no def. vol. or def. shape. Kinetic energy is the energy an object has due to its motion.

Review answers con’t 5. The kinetic theory of matter says that all particles of matter are in constant motion. 6.
