1. States of Matter Solid Liquid Gas A change in state always involves a change in temperature (average kinetic energy)

2. Solid Particles – – Very close together – Organized arrangement – “vibrate” in place – Lowest energy – Condensed state (low energy) – Definite shape and volume

3. Liquid Particles – – Medium distance apart – “slide over” each other – Slightly higher energy – Condensed state – (low energy) – Indefinite shape and Definite volume

4. Gas Particles – – Very far apart – Collide with each other – Highest energy – Indefinite shape and Indefinite volume

5. Gas Particles – – Very far apart – Collide with each other – Highest energy – Indefinite shape and Indefinite volume

6. Solution a mixture of two or more substances that is identical throughout, small particles can be physically separated composed of solutes and solvents the substance in the smallest amount and the one that dissolves in the solvent the substance in the larger amount that dissolves the solute Iced Tea Mix (solute) Water (solvent) Iced Tea (solution)

7. Parts of a Solution Solution- A homogenous mixture of two or more substances in a single physical state Ex. salt water or pop Solvent- Substance that does the dissolving in a solution (water) Solute- Substance that is dissolved in a solvent to form a solution (salt or sugar)

8. Aqueous Solution Water as the solvent

9. Concentration a measure of the amount of solute dissolved in a given quantity of solvent described as dilute if it has a low of solute (light) described as saturated if it has a maximum amount of solute (normal) described as concentrated if contains a lot of solute (dark)

10. How Much Will Dissolve? Solubility -is the max amount of solute that will dissolve at a specific/given temperature. The units for solubility are: grams of solute/100 grams solvent Saturated solution- -Contains the maximum amount of solute dissolved. Unsaturated solution- -Can still dissolve more solute Supersaturated solution- solution that is holding (or dissolving) more than it theoretically can; a “seed crystal” will make it come out
