CHEM 1111 Lecture Notes - Lecture 1: Human Eye, Chemical Property, Physical Property
Document Summary
Chapter 1 outline: 1. 1: chemistry in context, 1. 2: phases and classification of matter, 1. 3: physical and chemical properties, 1. 4: measurements, 1. 5: measurement uncertainty, accuracy, and precision, 1. 6: mathematical treatment of measurement results. Note that clouds are actually comprised of either very small liquid water droplets or solid water crystals; gaseous water in our atmosphere is not visible to the naked eye, Chemistry 1111 although it may be sensed as humidity. 1. 2 phases and classification of matter: matter - anything that occupies space and has mass. There are 4 states of matter (first 3 are most common: 1) a solid is rigid and possess a definite shape. Solid particles are held closely together in an ordered fashion: 2) a liquid flows and takes the shape of its container. Liquid particles are close together but are not held rigidly in position: 3) a gas takes both the shape and volume of its container.
