CHEM 151 1st Edition Lecture 3 Outline of Last Lecture I. What is Chemistry?II. PropertiesIII. Separation Methods Outline of Current Lecture IV. Differentiating CharacteristicsV. Phase TransitionsCurrent LectureIntensive Properties can be used a differentiating characteristics of a substance.Examples of Intensive Properties:- Density- Boiling point- Melting point- Surface tension- Heat capacity- Specific conductivity- Viscosity- SolubilityA common method used to separate a substance is to add heat and observe the affect. Heat and light are simple energy sources. Heat is an example of thermal analysis.Light is an example of spectroscopic analysis. (spectroscopy) Thermal Analysis is based on analyzing the changes in properties as the temperature is increased. During a phase change, temperature remains the same. These notes represent a detailed interpretation of the professor’s lecture.
