1. What are two properties used to describe matter?

•Mass

And

•Volume

2. What are the states of matter and their differences in terms of kinetic energy?

• Solid – has definite shape and definite volume particles vibrate in place; very low KE

• Liquid – has definite volume and indefinite shape; low KE• Gas – has indefinite shape and volume

Particles can expand to fill container;high KE• Plasma - has indefinite shape and volume ;

Highest KE

3. Which state of matter has definite volume and definite shape and is most resistant to compression?

•SOLID

4. Which state of matter has definite volume and indefinite shape?

•LIQUID

5. Which state of matter can take the shape of its container and is highly compressible?

•GAS

6. List three examples of matter.

•ROCK

•AIR•STEAM

7. What is not matter (list three things)?

•LIGHT

•HEAT•ENERGY

8. Define and give examples of the chemical properties of matter.

Chemical properties – the ability of a substance to undergo a

change that transforms it into another substance

Examples - Reactivity DecompositionpH CombustibilityToxicity

9. Define and give examples of the physical properties of matter.

• Physical property –• A characteristic that can be observed without

changing the identity of the substance• Examples :

• Solubility• Viscosity• Texture• density

10. Boiling point of a substance can be increased by increasing _____________________.

•PRESSURE

11. Explain the differences between intensive and extensive physical properties. List examples of both.

• INTENSIVE properties – do Not depend on amount of matter

• Examples: Density , conductivity, color• EXTENSIVE properties – do depend on amount

of matter• Examples: mass , volume

12. Classify the following as extensive or intensive properties:

• conductivity• silver• metallic • density • mass • melting point

• Intensive• Intensive• Intensive• Intensive• Extensive• Intensive

13. Which state of matter is most resistant to compression?

•Solid

14. What are mixtures?

•A physical combination of two or more substances, each of which retains its own properties

15. List the types of mixtures and give a definition of each.

• Homogeneous mixture- a physical combination of substances that has uniform composition throughout

• Example: salt water• Heterogeneous mixture- a physical

combination of substances that does not have a uniform composition

• Example: raisin bran

16. Salt water is what type of mixture?

•Homogeneous mixture

17. Evaporation, distillation, filtration, and chromatography are all techniques for separating

what?

•A mixture

18. What physical property would help you separate a mixture of isopropyl alcohol and water?

Boiling point

19. Density is what type of physical property (intensive/extensive)?

Intensive

20. Density (does / does not ) depend on amount of substance.

Does not

21. What is the formula for density?

•Density = mass / volume

•D = m v

22. Density will decrease if Massstays the same and volume

increases.

23. Which state of matter contains the most amount of kinetic energy?

•Gas phase• (followed by plasma phase)

Know the hierarchy of matter

Which particle diagram best represents a single element?

•A

2. Which particle diagram represents a single compound?

•B

3. Which particle diagram represents a mixture of elements?

•C

4. Which particle diagram represents a mixture of compounds?

•D

5. Which best describes the composition of the sample?

C.A mixture of compounds

6. Which best describes the composition of the sample?

•A•A mixture of elements and

compounds

25. Distinguish between 4 states of matter.

• Drawing 1 =• solid• Drawing 2 =• gas• Drawing 3 =• plasma• Drawing 4 =• liquid

Distinguish between solution, colloid, and suspension.

• Drawing 1 = • solution• Drawing 2 =• suspension• Drawing 3 = • colloid

A heterogeneous mixture always contains

C.Two or more substances

that are visibly distinguishable

A thoroughly mixed homogeneous mixture of substances in a single phase is

AA solution

A mixture that contains particles that settle out is

•D• A

suspension

Particles are in a dispersed phase and do not settle out

•A

•A colloid
