1. By Akum Deol = = Molecule Electron Heat= Picture = Example Key

2. Solid molecules are tightly packed and have the least amount of energy. Facts: Solids have definite shape, volume, and density.

3. Melting Adding the amount of energy

5. Liquid molecules are loosely packed but have medium amounts of energy. Facts: Liquids don't have definite shape but have definite volume and density.

6. Evaporating Adding the amount of energy

8. Gas molecules spread out to fill the entire space and move freely. And have lots of energy. Facts: Gasses don't have definite shape, volume or density.

9. Condensation Decreasing the amount of energy

11. Now the Gas is a Liquid

12. Freezing Decreasing amount of energy

14. Liquid is now a solid

16. Ionization Adding the amount of energy

18. Plasma molecules have extremely high level of energy and are electrically charged. Fact: Plasma don't have any definite shape, volume or density. Plasma is made 99% of the universe. But on Earth Plasma is rare.

19. Deionization Decreasing the amount of energy

21. Plasma is now a gas

22. Adding the amount of energy Sublimation

24. The solid is now gas

25. Decreasing the amount of energy Deposition

27. The gas is now a solid
