Terms | Definitions |
|---|---|
 gas | a substance with little intermolecular attraction |
| liquid | a substance with strong intermolecular attraction |
| solid | a substance with very strong intermolecular attractions |
| solid | a ________ has a definite volume and shape. Its particles are not free to move. particles are close but not in fixed positions |
| liquid | a _______ has a definite volume but indefinite shape. Its particles are close and free to move. |
| gas | a ______ neither has a definite volume nor shape. Its particles are at great distances and free to move. |
| crystalline solid | a highly regular arrangement of a solid's components |
| unit cell | the smallest portion of a crystal lattice that shows the 3-D pattern of the lattice |
| amorphous solid | a disorder in a solid structure (glass, plastic) |

| solution | a homogeneous mixture that is made of solutes and solvents |
| solute | dissolved substance in solution |
| solvent | dividing medium in solution (water in soda) |
| solubility | the ability of something to dissolve into something else |
| increases | solubility of solids ______ with temperature |
| speed | the _____ of solids dissolving increases with the surface area of a solid |
| decreases | the solubility of gases _______ when temperature increases |
| increases | the solubility of gases ________ with pressure above the solution |
| solids | _______ dissolve best when: heated, stirred or ground into small particles |
| gases | _____ dissolve best when: the solution is cold or the pressure is high |
| electrolyte | a substance whose aqueous solution conducts an electric current (tap water, actic acid) |
| nonelectrolyte | a substance whose aqueous solution does not conduct an electric current (pure water, sugar) |
| suspension | particles are so large that they settle out of solvent if not constantly stirred (mud, smog, paint) |
| colloid | particles are intermediate sized between those of a suspension and solution (smoke, mayonnaise, clay) |
| tyndall effect | if something scatters light it is a colloid. if it does not scatter light, its a solution |
