|
|

|---|---|---|---|---|---|
| Condensed Phases | liquids and solids
🗑
|
||||
| Liquids | have def volumes, can't be expanded/compressed, disorder, molecules can evaporate and diffuse
🗑
|
||||
| Solutions | liquids can mix to form ____
🗑
|
||||
| Miscibility | degree to which two liquids can mix
🗑
|
||||
| Emulsion | when two immiscible liquids are shaken to make a homogeneous mixture
🗑
|
||||
| Solids | strong attractive forces, molecules held tightly together, vibrate about fixed positions, dense shape/volume, crystalline or amorphous
🗑
|
||||
| Crystalline | an ordered structure; 3-D geometric arrangement with repeating patterns
🗑
|
||||
| Amorphous | like glass; no 3-D arrangement
🗑
|
||||
| 2 types of crystalline | metallic and ionic crystals
🗑
|
||||
| Ionic Crystals | high bp and mp, poor conductivity, no discrete molecules, aggregates of ions
🗑
|
||||
| Metallic Crystals | metal atoms packed tightly, single element, high mp and bp, strong covalent bonds
🗑
|
||||
| Unit Cells | 3 types, simple cubic, body-centered cubic, and face-centered cubic
🗑
|
||||
| Evaporation/Vaporization | liquid to gas; a cooling process
🗑
|
||||
| Condensation | gas to liquid; pressure forces gas molecules back into liquid phase
🗑
|
||||
| Vapor Pressure | equilibrium reached btwn vaporization and condensation. rates are equal
🗑
|
||||
| boiling point | temp at which the vapor pressure equals the external pressure
🗑
|
||||
| Fusion/Melting | solid to liquid; occurs at melting point
🗑
|
||||
| solidification/crystallization/freezing | liquid to solid; occurs at freezing point
🗑
|
||||
| Sublimation | solid to gas directly; dry ice
🗑
|
||||
| Deposition | gas to solid directly
🗑
|
||||
| Gibbs Function | G must be zero for an equilibrium so for sublimation, Gs=Gg
🗑
|
||||
| Triple Point | point on phase diagram where all three phases are in equilibrium
🗑
|
||||
| Critical Point | Point B where the temp and P causes there to be no distinction btwn liquid and gas
🗑
|
||||
| Raoult's Law | one can determine the relationship btwn vapor pressure of vapor A and concentration of liquid A in soln
🗑
|
||||
| Freezing-Point Depression | Tf= Kf(m); m is molality
🗑
|
||||
| molality | mol solute/kg solvent
🗑
|
||||
| Boiling-Point Elevation | Tb = Kb(m)
🗑
|
||||
| Osmotic Pressure | pressure exerted to counterbalance tendency of water to flow across membrane; high to low concentration; = MRT, M is molarity
🗑
|
||||
| Molarity | M; mol/L (n/V)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
