Chem 1061 Lecture 1 Outline of Last Lecture I. (no previous lecture; first day of class)Outline of Current Lecture 1. 1.1 Some Fundamental DefinitionsThis is some basic terminology to understand to start this course.2. 1.4 Measurement and Chemical Problem SolvingThis is a beginning into problem solving in chemistry using conversion factors to go between different measurement units.Current Lecture1.1 Some Fundamental DefinitionsMatter: anything with mass that occupies spaceProperty: characteristics describing a substanceChemistry: the study of matter and its properties, changes that matter undergoes, and the energy associated with these changes.Chemical/Physical Properties and Changes:I. Physical a. Properties: any property a substance shows by itself. Examples include density and the melting point of water.b. Changes: when a substance alters its physical properties but not its composition. Examples include ice melting into water.II. Chemicala. Properties: any properties of a substance as it changes into or interacts with another substance. Example would be flammability.b. Changes: when a substance is converted into different substances. Example would be paper burning. 1.4 Measurement and Chemical Problem SolvingAll answers in Chemistry need a NUMBER and a UNIT (Example: 13.68g/cm^2)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.We convert from one unit to another using conversion factors. Sample Problem: How long does it take to drive to Chicago if it’s 400 miles away and you drive 70mph? (Assuming you maintain a constant speed and do not stop.) 400 Miles x 1 hour/70 miles = 5.7 hoursUnits of Measurement:In Chemistry we use SI units, which is a revised system of the Metric System. In your textbook, Table 1.2 shows SI Units and conversions are found on Table
