Answer 1

Vaporization

Question 2

Properties of

Solids

Answer 2

have a definite shape and a definite volume

Question 3

properties of plasma

Answer 3

99.9 percent of matter in the universe is made of plasma
has an indefinite shape and an indefinite volume.
plasma has an electrical charge.
Most of the plasma in the universe is found within stars.

Question 4

solid to gas

Answer 4

Sublimation

Question 5

The particle theory

Answer 5

1 all matter is made of tiny particles
2 particles have empty spaces between them
3 particles are moving randomly all the time
4 particles move faster and spread farther
apart when they are heated
5 particles attract each other

Question 6

plasma to gas

Answer 6

Ionization

Question 7

Pure substance

Answer 7

Matter that contains only one kind of particle

All parts of the substance are the same throughout and have the same properties.

Question 8

gas to liquid

Answer 8

Condensation

Question 9

Compound

Answer 9

Contains particles that is a mix of two or more different elements

Question 10

Homogeneous

Answer 10

a mixture that looks like pure substance; a uniform mixture of two or more substances

Question 11

Recombination

Answer 11

gas to plasma

Question 12

Heterogeneous

Answer 12

a mixture with different parts that you can see

Question 13

Solutions

Answer 13

Solutions are made up of two or more substances, but have the same appearance.

Question 14

Solubility

Answer 14

the ability of solute to dissolve and form a solution when added to a solvent.

Question 15

Soluble vs. Insoluble

Answer 15

Soluble: the solute is capable of dissolving in a certain solvent
Insoluble: the solute isn’t able to dissolve certain solvent

Question 16

Classifying solutions

Qualitative

Answer 16

Concentrated : contains a large amount of solute and very little solvent.

Dilute: has very little solute dissolved into the solvent

Question 17

Quantitative

Answer 17

the exact amount of solute dissolved into a solvent

Question 18

Saturation

Answer 18

All solutions have a maximum amount of solute that will dissolve into a given amount of solvent at a given temperature.

Question 19

Unsaturated vs. Saturated vs. Supersaturated

Answer 19

A saturated solution is one that has been formed using the maximum amount of solute that will dissolve into a solvent, without adding more solvent or changing the temperature of the solvent.

A saturated solution can be cooled to a temperature where it forms a supersaturated solution, which contains more solute than would normally dissolve in the solution.

Question 20

Solubility and the Particle Theory

Answer 20

Particles have forces of attraction between them, and that they are in constant motion.
This means that in a solution, solute particles are bumping against other solute particles and solvent particles as well.

Question 21

Calculating Concentration

Answer 21

mass of solute (in grams)
Concentration = ————————————–
100 mL of solution

Question 22

Solubility formula

Answer 22

maximum mass of solute that will dissolve
(in grams)
Solubility = ————————————————
100 mL of solvent at a
certain temperature

Question 23

gas to solid

Answer 23

Deposition
