Term Organic Chemistry Definition The study of essentially all substances containing carbon. Term Inorganic Chemistry Definition The study of chemistry that specializes primarily in substances that do not contain carbon. Term Analytical Chemistry Definition The study of chemistry that is concerned with the compositions of substances. Term Physical Chemistry Definition The study of chemistry that is concerned with theories and experiments that describe the behavior of chemicals. Term Biochemistry Definition The study of the chemistry of living organisms. Term Matter Definition Anything that has mass and takes up space. Term Substance Definition That matter with a uniform and unchanging composition. Term The Four States of Matter Definition Solid (i.e. rocks), Liquid (i.e. water), Gas (i.e. hydrogen), and Plasma (i.e. lightning). Term Vapor Definition Gaseous state that can be solid or liquid at room temperature. Term Gas Definition Gaseous state at room temperature. Term Physical Property Definition Characteristic that can be observed or measured without changing the sample's composition (i.e. shape, solubility, and hardness). Term Chemical Property Definition Characteristic that must change a sample's composition in order to notice the change (i.e. ability to rust and flammability). Term Intensive Property Definition A characteristic of a substance that remains the same no matter how much of it there is (i.e. density). Term Extensive Property Definition A characteristic of a substance that changes depending on the amount of the substance (i.e. mass). Term Phase Change Definition A chemical change that occurs when matter transitions from one state to another. (i.e. gas --> liquid, liquid --> solid, etc). Term Chemical Change Definition A process that involves substances changing into new substances. Term The Law of Conservation of Mass Definition Mass is neither created nor destroyed during a chemical reaction - it is conserved. Term Definition
