Chapter 13: State of Matters

In chapter 13, we learned about the properties and assumptions of gases, and factors that affect the gas pressure. Gases are composed with small particles, hard spheres. It has insignificant volume which compared with the distance to the containers in liquid and solid. The motion in gas is very rapid, random and constant, it collides with each other to another particles. All collisions in gas are elastic that transferred from one to another without loss. The temperature and KE are proportion that when temperature increases, the KE should be decreases, but when temperature decreases, KE needs to be increases
