Matter

Question 1

What are the three states of matter?

Answer 1

Solid, liquid or gas.

Question 2

What are the basic properties of matter?

Answer 2

Shape, mass and volume.

Question 3

What is mass?

Answer 3

The amount of matter an object has and the volume is the amount of matter the object takes up.

Question 4

How do atoms look like in solid objects?

Answer 4

They are closely packed together. They hold the solid in a shape that does not change.

Question 5

Why are solids easy to recognize?

Answer 5

They have a definite shape, mass and volume.

Question 6

How are liquids different from solids?

Answer 6

They do not have a definite shape but they have mass and volume, their atoms are close together like solids however the atoms move around and therefore liquids change shape by flowing,

Question 7

Do gases have a definite shape or volume.

Answer 7

No. They will take the shape of their containers just like liquids.

Question 8

How are the atoms in a gas.

Answer 8

They are spread further apart than a solid or a liquid which allows them to move freely. If a gas is not in a container it will spread out indefinitely.

Question 9

Name some types of gases in the earth’s atomosphere?

Answer 9

Oxygen, Carbon dioxide, nitrogen, water vapor, helium.

Question 10

Name a substance that can become all three states of matter

Answer 10

Water - solid as ice, liquid as water, gas when it evaporates.

Question 11

All matter is made up of tiny particles - what are they called?

Answer 11

Atoms

Question 12

Definition of volume?

Answer 12

The amount of space that matter takes up.

Question 13

Definition of mass?

Answer 13

The amount of matter an object has.

Question 14

Liquids take the shape of their (blank)?

Answer 14

Container

Question 15

What state of matter does not have a definite shape or volume?

Answer 15

Gas

Question 16

What state of matter does not have a definite shape but has a definite volume?

Answer 16

Liquids

Question 17

What state of matter has a definite shape and volume?

Answer 17

Solids.

Question 18

Example of solids?

Answer 18

Chair, ice

Question 19

Examples of liquids?

Answer 19

Milk, juice

Question 20

Examples of gas?

Answer 20

Oxygen, Helium

Question 21

Solid ice is (blank) when it changes into a liquid?

Answer 21

Melting

Question 22

What physical properties of matter can you observe?

Answer 22

Shape. Volume, and mass

Question 23

What is a physical change? Give examples.

Answer 23

A physical change is a change in matter that changes the appearance or form of a substance but a new substance is not produced. Such as crumpled paper, ice melting, broken pencil, ice cream melting.

Question 24

What is a chemical change? Give examples

Answer 24

A chemical change is a change in matter that produces a new substance with new properties. Some evidence of chemical changes taking place are a gas is produced, changes in temperature, odor or colour. Such as: a rusted nail, burning wood, baking powder mixed with vinegar, baking cookies.

Question 25

Atoms that’s are joined together are called?

Answer 25

Molecules

Question 26

What happens to water when it evaporates?

Answer 26

It turns into a gas

Question 27

Since you can pour sand into a cup, why isn’t it a liquid?

Answer 27

No. Each piece of sand is a solid but the pieces are so small that when you pour them, they take the shape of the container. Each grain of sand has a definite shape mass and volume

Question 28

You can’t usually see gases in the air. How can you observe gases without seeing them?

Answer 28

Air movement. Wind mill. Wind on face. You can also measure temperature and humidity.

Question 29

Does air have mass?

Answer 29

atter is something that has volume (takes up space) and has mass (*can be weighed). Air does take up space, even if we can’t see it, and air has weight, even if we can’t feel it – and both of these properties can be observed and measured. Example balloon
