Matter Changing States

OK, smarty, so you’ve already learned about the three basic states of matter. Well, do you know the boiling point of water in degrees Celsius AND Fahrenheit? Or what “heat of fusion” means? If not, then the BrainPOP movie on matter changing states is for you! Tim and Moby will tell you all about the energy that state changes require, and the effect that extra energy has on atoms and molecules. You’ll learn about sublimation, which occurs when a solid melts directly into a gas, and also about condensation, when gas turns into liquid. A watched pot never boils--so get away from the stove and watch this movie while you wait!
