Ch 04.1: Physical Properties of Matter

Ch 04.1:
Physical Properties of Matter

At the end of this lesson, you will be able to:
1. define the term physical property
2. give examples of physical properties of matter

physical property

- a property of matter that can be measured or observed without matter changing to an entirely different substance
- can be detected by the senses

What differences between snow and sand can you detect with your senses?

You can see that snow and sand have a different color.

You can feel that snow is softer than sand.

Both color and hardness are physical properties of matter.

What are some physical properties of this copper wire?

• ability to conduct heat

• ability to conduct electricity

• malleable - able to be shaped

• ductile - can be rolled and stretched into long thin shapes

What are some physical properties of this copper wire?

Both of these observations are examples of physical properties:

• solubility - the ability to dissolve in other substances

• density - how closely packed the particles of matter are to each other

This is lemonade. It contains dissolved sugar. The ice cubes float at the top because they are less dense than the lemonade.

Did you know that water can boil, freeze, and melt?

Which of these would be a physical property of water?

• boiling point

• melting point

• freezing point

All of these are physical properties of matter!

• boiling point - the temperature at which a substance boils

• melting point - the temperature at which a substance melts

• freezing point - the temperature at which a substance freezes
