September 27, 2007 Homework : Memorize first 38 elements of periodic table Memorize Section D: Tables 1-4 A- 2, 5, 10, 14, 17, 21, 23, 24, 30 B- 2, 4, 7, 11, 15, 19, 21 Science is a systematic and controlled extension of common sense (still different from common sense) 4 Methods of Knowing : Method of Tenacity Method of Authority Priori Method (Intuition) Method of Science- one that is most focused on in this class Science is : Static View : Science is an activity that contributes to systematized info. to the world Heuristic View : Serves as a base for further scientific theory and research Kinetic Molecular Theory : Gases - constant random motion/movement Liquids - volume is fixed but shape is not (still requires kinetic energy)

Unformatted text preview: Solids- fixed volume and fixed shape Properties of Matter : Physical : something you can observe without changing identity Intensive- does NOT depend on sixe of sample (EX: temp., density) Extensive- does depend on size (EX: mass, volume) Chemical : ability of a substance (or mixture) to change Base Units : Length- meter (m) Mass- kilogram (kg) Time- second (s) Electric Current- Ampere (A) Temperature- Kelvin (K) Chemical Amount- mole (mol) Luminous Intensity- candela (cal) Derived Units- Combined Units Examples: Newton= (kg)(m)/s 2 Force= (m)(a) = (mass)(acceleration) Joule= (Newton)(m) = (kg)(m 2 )/s 2 Kinetic= E k = mv 2 Potential= E p = q 1 q 2 / 4 e r...
