In this lesson, we will learn what happens to the behaviour and arrangement of particles when they are heated or cooled. We will also investigate some uses of these properties such as cooling gases in order to store them.
In this lesson, we will learn about what happens when substances are heated or cooled enough to change state. We will learn about the four main state changes and identify examples of each of them.
