Unformatted text preview: Dr. Pustam September 24, 2009. Chem 127 - Fall 2009 Chapter 1 Outline 1. Learn the Fundamental definitions (Section 1.1). You need to be able to differentiate between a physical and chemical property and physical and chemical changes, see Sample Problem 1.1 and 1.2 on pg. 5 and 7. There are three states of matter — solids, liquids and gases. Read and learn the characteristics of the states of matter. Know the differences between potential and kinetic energy and be able to give examples. Understand what energy conservation is about. 2. A study of the Scientific Method (Section 1.3) See Figure 1.6 in text on pg. 13. Understand the steps of the scientific method and be able to distinguish between a hypothesis and a theory. 3. Solving Chemical Problems (Sections 1.4, 1.5) Measured quantities have units. You should be able to convert from one unit to another using conversion factors. Sample problem 1.3 on pg. 17 is very useful. Understand the approach used and try to develop yours. Practice this by working the problems in your lab manual in Experiment 1. Learn the SI units (Table 1.2) as you will be meeting these throughout the book. Also learn the prefixes used (Table 1.3). Read sample problems 1.4, 1.5, 1.6, 1.7. Learn how to convert fiom degree Celsius to Farenheit and degree Celsius to Kelvin. Know how to determine density and what are its units. 4. Measurements and Uncertainty (Section 1.6) Learn how to express uncertainty. ‘ Learn the rules associated with significant figures and be able to add, subtract, multiply and divide numbers with the correct numbers of significant figures. This will be useful in lab, when you will express your measurements to the appropriate number of significant figures. Understand the difference between precision and accuracy as well as random and systematic errors. Suggested problems ~n Cha ~2,—r4,y§,;3’,,26, , 34, gay iii/1);“ s! ytsesswaaesaa ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
