Question 12

Pure substance

Answer 12

Matter that has a uniform and definite composition

Question 13

Physical property

Answer 13

A characteristic of a substance that can be observed or measured without changing the identity of the substance (color, hardness, malleability, solubility, electrical conductivity, density, melting or boiling point, magnetism, etc.)

Question 14

Extensive property

Answer 14

A property depending on the amount of matter in a sample (mass, density, volume, etc.)

Question 15

Mass

Answer 15

Measure of the amount of matter that an object contains

Question 16

Volume

Answer 16

Measure of the space an object takes up

Question 17

Intensive property

Answer 17

Property depending on the type of matter in a sample, not the amount (electrical conductivity, color, temperature, density, solubility, etc.)

Question 18

Solid

Answer 18

Form of matter that has a definite shape and volume

Question 19

Liquid

Answer 19

Form of matter that has a definite volume, but indefinite shape

Gas

Answer 20

Form of matter that has indefinite shape and volume

Question 21

Vapor

Answer 21

The gaseous state of a substance that is a solid or liquid at room temperature

Question 22

Physical change

Answer 22

Change to a sample of matter in which some properties of the material change, but the identity of the matter doesn’t

Question 23

Chemical property

Answer 23

Describes the ability of a substance to undergo a specific chemical change

Question 24

Words used in a chemical change

Answer 24

Burn, rot, explode, decompose, ferment, rust, etc.

Question 25

Chemical reaction

Answer 25

Process that occurs when one or more substances are changed into one or more new substances

Question 26

Reactant

Answer 26

Substance that is present at the start of a chemical reaction

Question 27

Product

Answer 27

Substance that’s present at the end of a chemical reaction

Question 28

Visual clues that a chemical reaction is taking place

Answer 28

Change of color, gas produced, solid product (precipitate) is produced (could be cloudiness), visible transfer of energy occurs in the form of light

Question 29

Precipitate

Answer 29

Solid product that forms from a reaction and settles out of a liquid mixture
