1. Chapter 12 Properties of Matter
Lesson 3
What are Physical and Chemical Properties?

2. Main Idea Matter has different physical and chemical properties.
Physical and chemical properties are used to describe and classify matter.

3. Physical Properties
color
shape
texture
density
size

4. Shape How would you describe the shape of:

5. Size
huge
tiny
small
large
big
massive

6. Texture rough smooth silky bumpy hard soft
Texture is how the object feels.
rough
smooth
silky
bumpy
hard
soft

7. Density
Density describes how much matter is in a given space, or volume.
If you know the mass and volume of an object, you can calculate the object’s density.

8. The density of a substance determines whether it will float or sink in water or another liquid.

9. Chemical Properties
A chemical property is a characteristic of matter that can be observed only when matter is changed into a new kind of matter.

10. Chemical Properties
The ability to burn
The ability to rust

11. Chemical Properties
The ability to tarnish
The ability to cook
