Test p

Question 1

the three rates of increasing the rate of a dissolving process.

Answer 1

Heating, stirring, and decreasing the size of the particles.

Question 2

the three steps of dissolving

Answer 2

Dissociation, solvation, and diffusion

Question 3

the (5) properties of a solution

Answer 3

Solutes cannot be filtered out of a solution (particles are too small)
Solutes do not settle out of a solution (unless it’s a super solvent)
Solutions are not uniform (You cannot see the parts)
Solutions are not chemically combined
A solution can vary in its concentration.

Question 4

the parts of a solution

Answer 4

Solute, solvent

Question 5

Know the three intermolecular forces and how they are ordered from strongest to weakest.

Answer 5

Hydrogen bond, dipole dipole, and dispersion

Question 6

Know adhesion vs cohesion.

Answer 6

Cohesion is the attraction between particles of the liquid. Adhesion is the attraction between particles of liquid and other material. Adhesion is attracted to the side while cohesion is attracted to itself.

Question 7

how does surface tension break?

Answer 7

Through surfactants like soaps.

Question 8

Boyle’s Law:

Answer 8

Increased pressure decreases volume and vise versa. Inverse relationship. P1V1=P2Vs

Question 9

Charles’s Law:

Answer 9

When the pressure on a sample of a dry gas is held constant, the kelvin temperature and the volume are directly related. Volume increases and temp increases/volume decreases and tempt. Decreases. Direct relationship. Equations: V1/T1=V2/T2

Question 10

Gay-Lussac’s Law

Answer 10

Law Pressure is directly proportional wo kelvin temperature for a fixed mass of gas held in a constant volume. Temp increases as pressure increases and vise versa. DIrect relationship. P1/T1=P2/T2

Question 11

Avogadro’s Law:

Answer 11

The volume of a gas maintained at constant temp. And pressure is directly proportional to the number of moles of the gas.
Combined Gas Law P1V1/T1 = P2V2/T2

Question 12

effects solutes have in a solution

Answer 12

Decrease vapor pressure, freezing point and increases boiling pt (no math)

Question 13

Amorphous and crystalline solids.

Answer 13

Crystalline Solids: Naturally occurring orderly shapes, forming distinct 3D patterns, Shatters into distinct shapes, ionic, metallic, and some covalent solids are crystals.High boiling and melting points. Amorphous Solids: Have no distinct shape or underlying pattern. Satter into irregular fragments. Covalent compounds are usually amorphous.

Question 14

the different phase changes

Answer 14

(freezing, boiling, sublimation, and deposition etc)

Question 15

the main difference between boiling and evaporation.

Answer 15

Boiling is the change from liquid to gas with heat application while evaporation occurs in a non-boiling liquid.

Question 16

Know the surface tension def.

Answer 16

The elastic skin that forms on the surface of liquids. Produced by the imbalance of intermolecular forces on the surface of the liquid.

Question 17

How does surface tension break?

Answer 17

Through surfactants like soaps.
