CHM 1430 Study Guide - Final Guide: Boiling Point, Bromine, Sterling Silver
Document Summary
Properties are either intensive or extensive either intensive or extensive based on whether property depends on amount or not intensive. Not dependent on the amount of material present. Can be used to help identify materials. Ex: melting point, boiling point, density extensive. Dependent on the amount of material present. A change in which the material is chemically identical before and after. Physical change of state: melting (s->l), vaporization (l->g), condensation (g->l), freezing (l->s), sublimation (s->g), and deposition (g->s) chemical change. Easily identifiable: bubbles, color changes, smells, temperature changes physical classifications of matter solid, liquid, gas solid. Has definite shape and definite volume liquid. Has definite volume but indefinite shape gas. Only state that is compressible compositional classification of matter. Matter can be classified by its components. Can you separate by a chemical process? two principles of matter. Cannot be separated by a physical process. Matter has a fixed composition, set of characteristic properties and behaviors.
