Chem 1211 1st Edition Lecture 2 Outline of Last Lecture I. MatterII. Scientific MethodIII. Scientific or Natural LawsOutline of Current Lecture I. States of MatterII. DefinitionsIII. Phase ChangesIV. PropertiesCurrent LectureI. States of Mattera. Solid- has a rigid shapeb. Liquid- they take the shape of their containerc. Gas- they completely fill the container that they are ind. Plasma (will not discuss much)II. Definitionsa. Macroscopic: can use senses to observe detailsb. Microscopic: details must be inferred III. Phase changesa. Freezing- liquid to solidb. Melting- solid to liquidc. Condensing- gas to liquidd. Evaporating- liquid to gase. Deposition- gas to solid (i.e. frost)f. Sublimation- solid to gasi. Sublimation, evaporation, and melting require heatIV. Propertiesa. Chemical properties- chemical changes (reaction; molecules change into differentmolecules)b. Physical properties- physical changes (i.e. phase changes)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.c. Extensive properties- independent of mass (i.e. temperature)d. Intensive properties- need to have mass associated with
