Document Summary
Chemistry the study of matter, its properties, the changes it undergoes, and the energy associated with these changes. Matter anything that has mass and volume. Composition (of matter) the types and amounts of simpler substances that make up the matter. Properties (both physical and chemical) characteristics that give each substance a unique identity. Physical properties properties that a substance shows by itself, without interacting with other substances. Chemical properties properties that a substance shows as it interacts or transforms into other substances. Scientific knowledge testable, reproducible, explanatory, predictive, and tentative (can change as new discoveries are made). Scientific method: conducting a hypothesis (a tentative explanation of facts and observations), test the hypothesis by performing an experiment (measurement collect data), hypothesis is revised, and the process continues based on the observations. When the hypothesis successfully predicts what will happen, we designate it as a scientific law. (scientific law a mathematical description of what will happen. )
