Physical Properties of Matter

Unit E Lesson 1

Matter

Matter is anything that takes up space.

Physical Property

Physical property is anything you can observe about an object by using your senses.

Three states of matter

Solids take up a specific amount of space and have a definite shape.

Liquid

A liquid has a volume that stays the same, but it can change its shape. A liquid takes the shape of any container it is put into.

Gas

A gas does not have a definite shape or a define volume. It takes up all the space in its container.

Lesson 2

Matter is made of atoms. Atoms are the basic building

blocks of matter.

How Particles are Connected

How Matter Changes States

Adding heat or taking heat away causes matter to change states. This is because adding heat makes the particles in matter move faster.

Evaporation

Evaporation is the process by which a liquid becomes a gas.

Lesson 3 Measuring Mass and Volume All matter takes up

space. The amount of space matter takes up is called its volume.

Mass

Mass is the amount of matter in an object. You can’t tell how much mass an object has if you just look at it. You have to measure to find out how much mass an object has.

Weight Weight and mass

are different. Mass is the measure of the amount of matter in an object. Weight is the measure of the force of gravity on an object

An object’s mass stays the same no matter where the measurement is taken. An astronaut’s mass would be the same on the moon as it would on Earth.

An astronaut’s weight on the moon would be 1/6 of what he or she weighs on Earth.

Tools for measuring mass and volume Using the right tools

makes measuring easy.

Comparing Mass and Volume Different kinds of

matter can take up the same amount of space but have different masses. A lime has about the same volume as an egg. But the lime has more mass.
