KMT? OMG! $200
What do the letters KMT stand for?
KMT? OMG! $400
KMT helps explain _____ with by assuming what
about all matter?
KMT? OMG! $600
The assumption tiny particles are in
constant rotational and translation motion
applies to which of the three: solid, liquid or
gas
KMT? OMG! $800
In what state of matter do IMF’s have the greatest effect on particles? Least?
KMT? OMG! $1000
Rank the phases of matter from least to greatest density?
Explain the order you chose.
KMT? OMG! $200-Answer
Kinetic molecular theory
KMT? OMG! $400-Answer
• The behavior of matter in the different phases of matter
• The KE is directly proportional to
temperature
KMT? OMG! $600-Answer
Liquids only
KMT? OMG! $800-Answer
Solids – mostGases - least
KMT? OMG! $1000-Answer
Gas, liquid, solid
Density is a measure of mass per unit of volume (g/cm3). The less mass or
material in a given area, the less dense it will be. Gases have the most space between particles, so less mass in a given area. This gives rise to a low density. Particles are more closely spaced as you go from gas to liquid to
solid.
Got Gas? $200
Define a gas
Got Gas? $400
Do gases have a high or low density
Got Gas? $600
Gases have the property of being able to diffuse. What
assumption(s) is this based on?
Got Gas? $800
Gases have the ability to be compressed. What assumption(s) is this
based on?
Got Gas? $1000
Gases are considered to be fluid. What
assumption(s) make this true?
Got Gas? $200-Answer
In random, ceaseless, translational
motion and takes the shape and volume of
the container
Got Gas? $400-Answer
Low
Got Gas? $600-Answer
Assumption 1 – gasses are in random, ceaseless motion
Got Gas? $800-Answer
Assumption 3 – space between particles is
very large
Got Gas? $1000-Answer
Assumptions 2 and 3 – collisions are elastic
and space between particles is very large
Liquids $200
Define a liquid
Liquids $400
What is molar heat of vaporization
Liquids $600
How is a pure liquid different from a liquid
mixture? Name the three types of liquid
mixtures.
Liquids $800
Name a property of a liquid and explain it using the assumptions
of KMT liquids.
Liquids $1000
These two liquids are ________.
If the red liquid is non-polar, and it was then mixed with water. The two would be ________.
Liquids $200-Answer
Rotational and translational motion and has a defined shape but take the
shape of the container
Liquids $400-Answer
The amount of energy it takes to vaporize or
condense 1 mole
Liquids $600-Answer
Pure liquids are composed of a pure substance (atoms, compounds, molecules)
Solutions, colloids, suspension – particle size increase in that order
Liquids $800-Answer
1.High density (compared to gas) - #1
2.Relative incompressibility - #13.Ability to diffuse - #1 and 34.Surface tension - #25.Freezing, melting, boiling,
condensation - #26.Shape determined by container,
set volume - #2 and 3
Liquids $1000-Answer
Immiscible
Immiscible
Solid $200
Define a solid
Solid $400
What can we use the common
lattice shapes for?
Solid $600
There are two main types of solids.
Which type is pictured here?
Solid $800
You have a solid that a high melting point. It is brittle. When it is
solid, I does not conduct electricity.
Which specific subcategory of solid
Solid $1000
Solids have a high density and are incompressible.
Explain these based on the assumptions for KMT
solids
Solid $200-Answer
Rigid particles with minimal, vibrational
motion and a set volume and shape.
Solid $400-Answer
Since the lattice shape is characteristic of a compound, we can use it
to identify.
Solid $600-Answer
crystalline
Solid $800-Answer
ionic
Solid $1000-Answer
KMT assumes that solids are closely packed together. For this reason, the space between particles cannot be compressed and solids have a high density.
Solutions $200
What do compounds break into when they are in
solution?
Solutions $400
What are the two components of a
solution?Define them.
Solutions $600
Name three things you can do to increase the rate at which a solid
will dissolve.
Solutions $800
How would you change temperature and
pressure to get the maximum amount of gas
to dissolve?
Solutions $1000
35 grams of magnesium chloride can dissolve in
100 grams of water? If you have 200 grams of water and 80 grams of sodium chloride were dissolved, what type of solution do you have?
Solutions $200-Answer
ions
Solutions $400-Answer
Solute – what is being dissolved (small amounts)
Solvent – does the dissolving (greater
amounts)
Solutions $600-Answer
1. Increase temperature2. Increase surface area
(crush up)3. Increase
agitation/stirring/mixing
Solutions $800-Answer
High pressure (Henry’s Law)
Low temperature
Solutions $1000-Answer
supersaturated
Potpourri $200
For each pictured, Identify the type of liquid
mixture.
Potpourri $400
What phase change is occurring? Is it endo or
exothermic?
Potpourri $600
Will these two dissolve each other? How do you
know?
Potpourri $800
Determine the pressure in atm if it reads
2,494 torr
Potpourri $1000
Are these the same substances? How do you know?
At 1.00 atm
Potpourri $200-Answer
Yellow – true solution
Red - colloid
Potpourri $400-Answer
Melting
Endothermic – energy absorbed, moving from low to high
energy state, energy must be absorbed
Potpourri $600-Answer
No!! – “likes dissolve like” rule
Non-polar – no Lone pairs of electrons, all atoms bonded to central atom are the same
polar – lone pair of electrons
Potpourri $800-Answer
3.28 atm
*don’t forget significant figures
Potpourri $1000-Answer
No, they have different boiling and melting points at the same
pressure
