Gases (Chapter 10)

Gases (Chapter 10). Rather than considering the atomic nature of matter we can classify it based on the bulk property: gaseous, liquid or solid. Gases are the most easily understood form of matter (we shall see why).

Chapter 10

Chapter 10. Chemical Quantities. Chapter 10 Section 1. The Mole. Measuring matter. We measure by three different methods Counting- How many there are. Volume- How much space they take up. Mass- How much they weigh. We have to know conversion factors to relate these different measurements.
