1. Chapter 2: Properties of Matter
Section 1: Matter has observable properties.

2. Physical Properties
Physical properties of a substance can be observed without changing the identity of the substance.
Density, mass, color, size, volume, and texture are examples of physical properties.

4. Density is the relationship between the mass and the volume of a substance.
Density= Mass ÷ Volume

6. Any change in a physical property of a substance is a physical change
Any change in a physical property of a substance is a physical change. The identity of the material remains the same during the change.
Examples of physical changes include cutting a material, breaking it, and changing its state.

8. Chemical properties describe how substances form new substances.
To observe chemical properties in a substance, you must see a chemical change.

9. To observe the combustibility of a piece of paper, for example, the paper must burn. The products that result from burning the paper differ in identity from the paper itself.

10. Signs of a chemical change include the production of an odor, a gas, or a solid and a change in temperature or color.

11. Other examples of chemical properties include reactivity, tendency to corrode, and toxicity.

12. Shape
Color Texture
Volume Size

13. Measuring an object’s mass does not change the substance to another substance.
Changing the shape of a substance does not transform the substance itself.

14. measurement;
amount of matter in a given volume
g/cm3, D = m/V

15. V= l x w x h
3 cm x 4 cm x 5 cm = 60 cm3.
D= m/V
D= 480 g/60 cm3
D= 8 g/cm3.

16. wool being transformed into a sweater,
stretching a rubberband,
breaking a piece of clay in half

17. When something burns, the substance changes into a new
substance, so it is a chemical change.

18. substances forming other substances
used to identify c. properties change of one into another
wood burning; iron rusting

19. Color Change Temp Change
Bubbles Formation Light Emission
