Document Summary
Chemistry: the field of study concerned with the characteristics, composition, and transformations of matter. Matter: anything that has mass and volume: mass is the amount of matter present (not the same as weight, volume is the amount of space something occupies. Includes all things both living and nonliving: various forms of energy (heat, light) are not considered to be matter. Physical states of matter (expected to know: solids: definite shape and volume o. Liquids: indefinite shape and definite volume: gasses: indefinite shape and volume. States of matter: the state of matter observed for a particular substance depends on its: Strength of the forced holding its structural particles together (don"t worry about it for now) Properties of matter: property: distinguishing characteristic of a substance that is used in its identification and description o. Characteristics of a substance that can be observed without changing the basic identity of the substance. Color, odor, physical state, melting point, boiling point, and hardness.
