Document Summary

Reading: read the following sections carefully: 1. 2 1. 9: skim section 1. 1, skip section 1. 10. What is chemistry: study of the properties of substances and how they react with one another. How do they differ from one another: microscopic implies detail at the atomic or subatomic levels which cannot be seen directly, macroscopic is the one we know by direct observations of physical properties such as mass, volume, etc. What does this say about the nature of scientific knowledge: scientific methods include hypothesis, experiments, law, and theory, it is a very iterative process, the nature of scientific knowledge is not 100% certain. How are they different: quantitative data is numerical data, qualitative data is observed data/general characteristics. What are the two parts of any measurement: value and unit. You should know the metric base units (and their symbols) for volume, mass, length, and temperature. You need to memorize the metric equalities on slides 33 and 34 (refer to table 1. 2).
