Episode Details

This lesson brings to life the amazing physical changes that are going on around us every day. From making coffee, to melting butter, to seeing condensation on your car in the morning, the chemistry of state or phase transitions is amazing to observe and understand. You will use a lot of what you already learned in previous lessons as you explore how substances behave differently as they change states (gas, liquid, solid). Although kinetic energy is the key ingredient that drives all these changes, there are other laws and forces that explain why substances behave differently when energy is applied. Molecules are always moving and this lesson will help explain the impact of that movement on you and how you interact with the world around you.
