Document Summary
Chapter 1: chemistry - the study of matter and changes that it undergoes, matter - anything that occupies space, scientists follow the scienti c method. Further experiments: substance - matter that has de nite composition, mixture - combination of 2 or more substances. Heterogenous: isn"t uniform, regions have different properties: solids, liquids, gases. Flammability: chemical change - is one that results in a change of composition. **a measured quantity must include a unit*: metric system includes units such as meter, liter, kilogram, si base units - designed for universal use by scientists. *a picometer is 1x10 -12 meters: mass is the measure of the amount of matter in an object or sample, atomic mass unit (amu) - used to express the masses of atoms and other small objects. *to get from celsius to kelvin - *c + 273 = k* *temperature in *f = (9*f/5*c x temp in *c) + 32*f*
