1. Kinetic molecular theory
A model that describes the behavior of ideal gases in terms of tiny particles that are in constant, random motion.
2. Boyle's Law
The volume, V, occupied by a sample of gas is inversely proportional to pressure,P, at constant temperature.

P1V1 = P2V2
3. Charles's Law
The volume, V, occupied by a sample of gas is directly proportional to its Kelvin temperature, T, at constant pressure.

V1/T1 = V2/T2
4. Gay Lussac's Law
• For sample of gas with a constant volume, its pressure, P, is directly proportional to its Kelvin temperature, T.
• P1/T= P2/T2
5. Vaporization
The process by which molecules of a volatile liquid break away or escape and go into the gas.
6. Condensation
The conversion of a vapor to a liquid by cooling the vapor.
7. Difference between vapor and condensation...
Vapors are gasses..

condensation is a liquid or solid formed from a gas cooling off...
8. Temperature Conversions
F = 9/C +32                     K = C +273

C = 5/9 (F - 32)                 C = K - 273
9. Solution

A system in which one or more substances are uniformly and homogeneously mixed or dissolved in another substance.
10. Solute
One of the components of a solution - the substance which has been dissolved.
11. Solvent
one of the components of solution - The substance which does the dissolving.
12. Soluble
Capable of being dissolved.
13. Solubility
Usually expressed as the maximum number of grams of a substance solute which will dissolve in 100 grams of solvent at a definite temperature.
14. Dilute Solution
Contains a small of solute in comparison to the amount of solvent.
15. Saturated solution
A solution which contains all the solute it can dissolve at a given temperature. (Rate of crystallization is equal to the rate of solution; an equilibrium has been reached).
16. Concentrated Solution
Contains a large amount of solute in comparison to the amount of solvent.
17. Unsaturated Solution
All solution containing less solute than it could normally dissolve at a given temperature.
18. Supersaturated Solution
Any solution containing more solute than it can normally hold or dissolve at a given temperature.
19. Miscible
20. Non - Miscible
21. Heterogeneous Mixture
22. Homogeneous Mixture
23. Dynamic Equilibrium
24. Percent Solutions
A solution whose solute and solvent have a definite relationship. A 5% solution of sugar contains 5 grams of sugar for every 95 grams of water.
25. Molar Solutions
Contains one mole of solute per one liter of solution.
26. Molal
Contains one mole of solute dissolved in 1,000 grams of solvent.
27. Normal Solutions
Contains one gram-equivalent weight of solute in which sufficient solvent has been added to make a total of one liter of solution. the equivalent-weight is taken as the gram-molecular weight of the substance divided by the total positive valence number.
28. True Solution
29. Suspention
A nonuniform mixture of insoluble particles which slowly settle on standing. Suspensions are usually opaque and cloudy.
30. Colloidal Dispersion
A suspension in which the suspended particles readily pass through ordinary filters and do not settle out on standing. Colloidal suspensions will reflect a powerful beam of light. This indication of the presence of colloid particles is called the Tyndall Effect.
31. Tyndall Effect
A beam of light passing through a colloidal solution.

Ex. The light at the movie theater that originated from the projection booth and ends at the screen.
32. Ionization
The Formation of ions from individual atoms.
33. Dissociation
The process whereby a chemical substance breaks up into simpler component parts (molecules or ions) when it melts or when it dissolves in a solvent.
34. Osmosis
The selective passage of a solvent through a semipermeable membrane.
35. Diffusion
the spontaneous mixing of gases at constant pressure.
