Classification of Matter

Question 1

Property

Answer 1

Characteristic that allows us to recognize a particular type of matter and to distinguish it from other types.

Question 2

Element

Answer 2

Pure substance that cannot be broken into simpler substances because it is composed of only one type of atom.

Question 3

Arrangement

Answer 3

Order

Question 4

Homogenous

Answer 4

Uniform (having the same properties) in every part.

Question 5

Heterogenous

Answer 5

With different properties in different parts.

Question 6

Phase

Answer 6

Any sample or part of a sample that is homogenous.

Question 7

Physical property

Answer 7

A property that can be observed without destroying or creating any substances.

Question 8

Atom

Answer 8

The smallest piece into which matter can be subdivided while still retaining its distinguishing properties.

Question 9

Substance

Answer 9

Matter that has distinct properties and a composition that does not vary from sample to sample.

Question 10

Mixture

Answer 10

Multiple substances mixed together.

Question 11

Density

Answer 11

Mass (in kilograms) per cubic metre.

Question 12

State

Answer 12

Form (solid, liquid, or gas) of matter.

Question 13

Viscosity

Answer 13

How thick a liquid is; “runny” liquids like water are less viscous, while “sticky” liquids like syrup are more viscous.

Question 14

Solubility

Answer 14

Maximum mass (in grams) of a solid that can dissolve in 100 ml of a liquid.

Question 15

Malleability

Answer 15

Ability of a solid to be hammered into and keep a new shape without breaking.

Question 16

Ductile

Answer 16

Ability of a solid to be drawn into a thin wire.

Question 17

Aqueous

Answer 17

Dissolved in water.

Question 18

Continuous

Answer 18

Able to be any value.

Question 19

Discrete

Answer 19

Able to be only certain values.

Question 20

Dissolve

Answer 20

Mix two phases to form one new homogenous phase.

Question 21

Compound

Answer 21

Pure substance that can be broken into simpler substances by breaking apart the atoms.

Question 22

Boil

Answer 22

Turn from a liquid into a gas by heating until bubbling.

Question 23

Evaporate

Answer 23

Slowly turn from a liquid into a gas without heating.

Question 24

Freeze

Answer 24

Turn from a liquid into a solid.

Question 25

Solid

Answer 25

Matter with a definite volume and shape.

Question 26

Liquid

Answer 26

Matter with a definitive volume but no definite shape; instead, it takes the shape of the container it is in.

Question 27

Gas

Answer 27

Matter without any definite shape or volume; instead, it takes the shape and volume of the container it is in.
