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 – most Gases - least

KMT? OMG! $1000-Answer Gas, liquid, solid Density is a measure of mass per unit of volume (g/cm 3 ). 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 - #1 3.Ability to diffuse - #1 and 3 4.Surface tension - #2 5.Freezing, melting, boiling, condensation - #2 6.Shape determined by container, set volume - #2 and 3

Liquids $1000-Answer 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 $ 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 temperature 2.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
