1. Change of State and Solubility
Chapter 3

2. 3 States of Mtter
Solid
Liquid
gas

3. Thermal Energy Heat energy
Thermal energy is the energy that makes atoms and molecules move

4. The more atoms and molecules move, the more room they take up.
When matter is heated, therefore, it expands
When matter is cooled, it moves less, and contracts.

6. Solid Particles are packed closely together Particles vibrate in place
Particles have a fixed volume and shape

7. Liquid Particles are freely moving
Particles have a fixed volume, but take the shape of the surrounding container

8. Gas
Particles do not have a fixed volume and take the shape of the surrounding container

12. Plasma: highest-energy state of
matter; consists of electrons and
positive atoms

15. Solid/Liquid
Melting: the process in which a solid is changed into a liquid
Freezing: the process in which a liquid is turned into a solid

17. Gas/Liquid Vaporization: the process of turning a liquid into a gas
Boiling: a type of vaporization in which large amounts of a liquid change into a gas at once
Evaporation: the type of vaporization that occurs when energetic particles burst through the surface of the liquid and escape
Condensation: the process in which a gas is turned into a liquid

18. Solid/Gas
Sublimation: the process in which a solid is converted directly into a gas
Deposition: the process in which a gas turns directly into a solid

20. Proteins
Some of the largest,
most complex molecules
of all

21. Solubility
Solubility is the ability of one material to be dissolved into another

23. Solutions
A solution is a mixture that is made when one material dissolves into another
2 parts:
Solvent: a gas, liquid, or solid in which another material is dissolved
Ex: Water: very good at dissolving things; universal solvent
Solute: material that is dissolved
Ex: salt, sugar

25. Soluble: a material is able to be dissolved
Ex: Salt is soluble in water
Insoluble: materials that are not able to be dissolved
Ex: a glass marble is insoluble in water

26. Saturation: when no more of a material (solute) will dissolve in a solvent
