1.1 The Study of Chemistry
Chemists are interested in the reactions and properties of matter and measure the changes from one state of matter to another. By analyzing the properties of matter, a chemist can design, modify, and improve the way a material function. We need a way to classify matter and must introduce terms that will allow you to communicate with a chemist.
1.3 Properties of Matter
1.3 Properties of Matter
In order for the properties of matter to take on meaning, a chemist must be able to quantify their measurements and communicate their results to other scientists. In 1960 a system was developed for the preferred metric units for use in science called SI Units. We will use these units throughout the course.

1.4 Units of Measurement
Now that we have emphasized the units we will be using, we need to come up with a system that will indicate to us, and more importantly, someone else who is reading our data, just how good our measurement is. Significant Figures tell us how good our data is.
