CHEM 1P Chapter Notes - Chapter 1: Luminous Intensity, International System Of Units, Kilogram
Document Summary
Chemistry: the study of the structure and behavior of matter, answers our questions about the world and helps create new materials and drugs. The scientific method: steps that scientists use to approach a question. Results published (others will repeat the experiment and accept/confirm or reject the study) If accepted, search for useful application of the new idea. The international system of measurement (si units: 7 base units from which other units are derived. Candela (luminous intensity: si units derived from base units. Volume, for example, isn"t a base unit but can be derived from meters (base unit for length); m^3 = volume. Liter (l) = 10^-3 of a cubic meter (10^3 liters per cubic meter: si units derived from metric preferences. Base units can be multiplied/divided by powers of 10 when attached to base units (kilo + meter) Temperature: measure of average motion of particles in a system. Water freezes at 0 c and boils at 100 c.
