Week 4: The Ideal Gas Laws and Acid/Base Reactions PHYSICAL STATES OF MATTER In this section, we will discuss the Ideal Gas Laws. First, we will review the properties of solids, liquids, and gases. Second, we will discuss the kinetic-molecular theory of gases, which explains why they are so unique compared to other states of matter. Finally, we will discuss gas law equations, and practice using them to solve for different parameters. This unit has many strong connections to our daily lives ...
