Lecture Outline PART 1: BASIC CHEMISTRY I. Definition of Concepts: Matter and Energy (pp. 25–27) A. Matter is anything that occupies space and has mass (p. 25). 1. Mass is equal to the amount of matter in the object. 2. Mass remains constant regardless of gravity. B. States of Matter (p. 25) 1. Matter exists in one of three states: solid, liquid, or gas. C. Energy (pp. 25 27) 1. Energy is the capacity to do work, and it exists in two forms. a. Kinetic energy is the energy of motion. b. Potential energy is stored energy. 2. Forms of Energy a. Chemical energy is energy stored in chemical bonds. b. Electrical energy results from the movement of charged particles. c. Mechanical energy is energy directly involved with moving matter. d. Radiant energy is energy that travels in waves. 3. Energy is easily converted from one form to another. II. Composition of Matter: Atoms and Elements (pp. 27–30)
