Chap 11 Flashcards
1
Q
Crystalline solids vs amorphous solids
A
- solid particles arranged in an orderly geometric patter
- Do not show a regular geometric pattern.
2
Q
Exception to densities of liquids less than those of solids
A
water: ice floats on water. So ice has a lower density.
3
Q
Another word for non-bonded interactions
A
intermolecular interactions.
4
Q
Boiling pt of polar molecules vs non-polar
A
polar molecules are greater.
5
Q
Dispersion forces
A
- fluctuations of electrons set up temporary dipoles which are responsible for dispersion forces.
6
Q
A dynamic process in equilibrium btn phases
A
it’s dynamic BCS molecules travel btn phases continuously.
7
Q
factors affecting the Rate of vaporization
A
- SA. higher SA = higher rate of vaporization.
- intermolecular forces: decreases vp
8
Q
Factors affecting vapor pressure
A
temp and intermolecular forces.
9
Q
Superheating vs supercooling
A
When temp is raised quickly, a liquid can exist in temperatures higher than its boiling point.
- liquids exist at temp lower than the freezing pt
