Cc different properties: science latin meaning to know , natural causes for national phenomenon, observe and measure methods of systematic investigation, methods of investigating biology. Types of logic: inductive reasoning, start with large number of specific observations to generalizations, seq observation pattern data analysis generalization, ex. Comparison: o = 3. 5 (most electronegative, h = 2. 1, s = 2. 5, c = 2. 5, n = 3. 0. Ch4: polar covalent bond, e- spend more time with one end of molecule than the other end, ex. Emergent properties of water: cohesion sticks to itself, ex. Surface tension measure of how difficult to stretch or break surface of liquid: surface molecules ordered, film a surface, adhesion sticks to something else, ex. Sweating: evaporative cooling, expands upon freezing, liquid water, ex.
