Chapter 2 Outline- Energy and Matter
(Temperature Scales, Pure Substances, and Mixtures)
Part I-
Key Vocabulary- For each word or phrase below, define it in your own words (paraphrase, do not copy from the study guide in the back!). Remember, examples are always helpful to clarify terms, but they are not definitions in themselves. If the word describes a measurement, make sure to provide the symbol as well as the definition. Especially important terms are starred with a *. If you require more space attach a clean sheet of paper to the back.
Example: Joule (pg. 57)- A unit of energy with the symbol (J). It doesn’t just measure heat energy but other forms as well. The Joule is a derived unit (made up of other SI base units).

Part II-
Fundamentals- Each chapter outline will have a fundamentals section that seeks to reinforce main concepts and skills through calculations, making tables, and doing other tasks. Please complete each part thoroughly.
1. List some of the temperatures for these typical situations
Example / Celsius (oC) / Fahrenheit (oF)Melting Ice
Room Temperature
Boiling Water
Surface of the Sun
Absolute Zero
2. Come up with your own (not out of the textbook) example of a chemical change. What makes your example a chemical change rather than a physical one?
3. Write the chemical symbols for the elements in order to complete the word it makes (longest word out of chemical symbols without repeating!)
1. Rhenium
2. Sulfur
3. Phosphorus
4. Oxygen
5. Nitrogen
6. Silicon
7. Bismuth
8. Lithium
9. Titanium
10. Einsteinium
