Matter

Question 1

Matter

Answer 1

Anything that takes up space and has mass.

Question 2

Physical Properties

Answer 2

One that can be observed, measured, or changed without changing the substance itself.

Question 3

mass

Answer 3

The amount of matter in an object or substance. You can find the mass of an object using a balance.

Question 4

Weight

Answer 4

A measure of the force of gravity on an object.

Question 5

What is the difference between Mass & Weight on the moon?

Answer 5

Mass would not change ,but the weight of an object would decrease due to the change of gravity.

Question 6

What are the 3 states of matter?

Answer 6

Solid, liquide, and gas.

Question 7

Solid

Answer 7

A state of matter in which the substance has a definite shape and a definite volume. Doesn’t change shape. EX. wood

Question 8

Liquid

Answer 8

A state of matter in which has a definite volume but takes the shape of its container. EX. water

Question 9

Gas

Answer 9

A state of matter in which the substance takes both the shape and volume of its container. EX. water vapor, steam

Question 10

Physical Change

Answer 10

A change from one form to another form without turning into a new substance. EX. a piece of paper is still a piece of paper even if you tear it into tiny pieces.

Question 11

Volume

Answer 11

The amount of space an object or substance takes up.

Length{L} X Width{W} X Height{H} = Volume{V}

Question 12

Density

Answer 12

The amount of mass in a known volume of an object or substance . If the density of an object is greater than the density of water, the object will sink. If the density of the object is less than the density of water, it will float.

Question 13

Constant

Answer 13

Something that doesn’t change.

Question 14

Boiling Point

Answer 14

The temp. at which a substance changes from a liquid to a gas. {100 c} EX. water to water vapor

Question 15

Melting Point

Answer 15

The tem. at a which a substance changes from a solid to a liquid. {0 c} EX. ice turning into water

Question 16

Freezing Point

Answer 16

The tem. at which a substance changes from a liquid to a solid. EX. water to ice

Question 17

Thermal Energy

Answer 17

The energy of moving particles in a substance. If you are taking away thermal energy freezing occurs. If you are adding thermal energy, melting occurs.

Question 18

Conductor

Answer 18

A material that allows energy to pass through easily. EX. metal, wires

Question 19

Insulator

Answer 19

A material that does not let heat energy or electricity pass through it easily. EX. cloth, wood, rubber

Question 20

Solubility

Answer 20

The ability of a substance to dissolve in to another substance.

Question 21

Appearance

Answer 21

Color size shape texture Lester (to see how she is a substance reflects light)

Question 22

Temperature

Answer 22

The amount of heat in matter.(measured in degrees Celsius)

Question 23

Magnetism

Answer 23

Ability to attract iron.

Question 24

Texture

Answer 24

How an object or substance feels to the sense of touch.

Question 25

Flexibility

Answer 25

Ability to bend.

Question 26

What do opposite poles do?

Answer 26

Attract.

Question 27

What do alike poles do?

Answer 27

Repel or push away.

Question 28

Name 6 physical properties?

Answer 28

Appearance, temperatures, mass, state of matter, magnetism, texture, flexibility, conduction, solubility, boiling point, melting point, buoyancy, density.
