Three Phases of Matter

Three Phases of Matter

Solid, Liquid, and Gas

Let's Review!

Multiple Choice

All matter is made of

• solids

• liquids

• gases

• atoms

Matter is anything that has mass (weight) and volume (size).

​

Multiple Select

Matter is anything that has

• shape

• mass

• molecules

• volume

MASS

(Weight)

Scientists use the word mass because weight can vary (change).

N= Newton, a metric unit of force, used also as a unit of weight (force due to gravity).

Mass is the amount of matter in an object.

​

Multiple Choice

The word____ is a simple way to explain mass.

• height

• space used

• weight

• distance

WHAT IS VOLUME?

​

Multiple Choice

The word ____ is a simple way to explain volume.

• height

• weight

• size

• mass

The larger the size, the more space it fills.

Volume relates to size.

Multiple Select

All matter has

• height

• volume

• shape

• mass

1. All matter has volume (size) and mass (weight)

All Matter Has Three Phases (states).

Solid, Liquid and Gas

Multiple Choice

Solids, liquids and gases all have mass and volume.

• True

• False

• Sometimes

Solids, liquids, and gases are all matter.

What does all matter have?

Multiple Select

All matter has

• shape

• volume

• density

• mass

Open Ended

All matter has mass (weight) and volume (size).

Solids, liquids, and gases are matter.

Therefore, solids, liquids and gases all have...

Matter has 3 phases (states).

Solid, Liquid, and Gas

Multiple Choice

The three phases of matter are

• volume, mass, shape

• solid, mass, gas

• mass, solid, liquid

• solid, liquid, gas

Multiple Select

Solids have definite shape. This means their shape

• can change

• is fixed

• doesn't change

• varies in size

Multiple Select

Solids have definite volume. This means

• the space they fill doesn't change.

• the amount of matter in them doesn't change

• the amount of weight they have doesn't change

• their size doesn't change

Multiple Choice

What explains why solids have definite shape and definite volume ?

• the arrangement of molecules

• the arrangement of weight

• the arrangement of shape

MOLECULES IN A SOLID VIBRATE IN PLACE.

LIQUIDS

Shape: Indefinite

Volume: Definite

Multiple Select

She just told you all liquids

• have volume

• have mass

• have shape

• have height

Multiple Choice

This video proves that liquids have

• indefinite (changing) mass

• indefinite (changing) volume

• definite (not changing)shape

• indefinite shape

That proves liquids have indefinite (changing) shape.

Multiple Choice

The prefix "in" (examples: indefinite, invisible, impossible) means

• the opposite

• the same

Liquids have indefinite (changing) shape.

What about their volume?

​

Liquids flow.

Multiple Choice

Liquids flow because they have

• molecules that are close and move around each other.

• molecules that vibrate in place

• molecules that are far apart and move rapidly

• molecules that are slimy

MOLECULES IN A LIQUID PHASE

Multiple Choice

How do molecules in solids move? They

• slide past each other.

• vibrate

• bounce all around

• don't move.

In solids, the molecules vibrate in place.

Gases

Shape: Indefinite

Volume: Indefinite

Molecules in a gas phase

Multiple Choice

Do gases have definite (not changing) shape?

• Yes

• No

• Sometimes

Multiple Choice

Do gases have definite volume?

• yes

• no

• sometimes

Review of Liquids and Gases

Multiple Choice

Multiple Choice

The prefix "in" (example: indefinite) means

• the same

• to enter

• the opposite

Multiple Select

Indefinite volume and indefinite shape means the size and weight

• do not change.

• do change.
