Document Summary
Chapter 1 keys to the study of chemistry. Chemistry: the study of matter and its properties, the changes that matter undergoes, and the energy associated with those changes; anything that has mass and occupies volume. Matter: the stuff of the universe; air, glass, planets, students anything that has mass and volume. Composition: the types of matter that has a defined, fixed composition. Matter occurs in three physical forms called states: solid has a fixed shape that does not conform to the container shape; are not defined by rigidity or hardness. Particles lie next to each other in a regular, three-dimensional array: liquid has a varying shape that conforms to the container shape, but only to the extent of the liquid"s volume; has an upper surface. Particles lie close together but move randomly around each other: gas has a varying shape that conforms to the container shape, but it fills the entire container, does not have a surface.
