CHM 2040 Lecture Notes - Chemical Energy, Kinetic Energy, Close-Packing Of Equal Spheres
Document Summary
Scientific method: structure determines properties, the properties of matters are determined by the atoms and molecules that compose it, atoms and molecules, atoms, molecules. Are fundamental buildings blocks of ordinary matter. Are two or more atoms attached together in a specific geometrical arrangement: attachments are called bonds, attachments come in different strengths, comes in different shapes and patterns. Physical and chemical changes: matter is anything that occupies space and has mass, we can classify matter based on its state and its composition. 2: crystalline solids, some solids have their particles arranged in patterns with long-range repeating order we call these crystalline solids. Chm 2040--0003: amorphous solids, some solids have their particles randomly distributed without any long- range pattern we call these amorphous solids. In the gas state, the particles have freedom of motion and are not held together: the particles are constantly flying around, bumping into each other and the container. Made of a single type of atom or molecule.
