Mrs Coffee Ch 3 States Of Matter

Front 1

31. Define exothermic change.

Back 1

31. It is a change that occurs when energy is removed from a substance.

Front 2

32. What are the four major states of matter?

Back 2

#32
1. Solid
2. Liquid
3. Gas
4. Plasma

Front 3

33. What are two forms of naturally occurring plasmas on Earth? (Short Answer)

Back 3

33. Lightning and fire

Front 4

28. What does Charles' Law say would happen to a balloon if you put in the freezer?

Why?

Back 4

28. It would shrink because if the temperature decreases, the volume (size) will also decrease.

Front 5

29. What process changes a liquid to a gas?

Back 5

29. Vaporization

Front 6

30. Tell what state ice, water, and steam are in.

Back 6

30. Ice is a solid.
Water is a liquid.
Steam is a gas.

Front 7

25. Compare endothermic and exothermic. (Short Answer)

Back 7

25. During endothermic changes, energy(heat) is added. During exothermic changes, energy (heat) is removed.

Front 8

26. What happens to the particles when a liquid becomes a gas?

Back 8

26. The particles break away from each other

Front 9

27. Describe the particles of a liquid.

Back 9

27. The particles are close together but are able to slide past each other.

Front 10

22. What state does matter have a fixed shape and volume?

Back 10

22. Solid

Front 11

25. Define condensation.

Back 11

25. It is the change from a gas to a liquid.

Front 12

24. What state is it that will take the shape of its container and has a fixed volume?

Back 12

24. Liquid

Front 13

19. According to Boyle's Law, what will happen to the volume of a gas inside a chamber sealed by a piston if the pressure is reduced?

Back 13

19. It will increase.

Front 14

20. What are three things that happens when a substance loses or absorbs energy?

Back 14

#20
1. Its temperature can change
2. The speed of the particles can change
3. Its state can change

Front 15

21. What are crystalline and amorphous examples of?

Back 15

21. Solids

Front 16

16. What state will not change shape in different containers?

Back 16

16. Solids

Front 17

17. Define vaporization.

Back 17

17. It is the change of state from a liquid to a gas.

Front 18

18. According to Charles' Law, if the temperature of a gas increases, what happens to the volume?

Back 18

18. The volume will increase also.

Front 19

13. What are particles like in a gas state?

Back 19

#13
1. They move independently of each other.
2. They move fast enough to break completely away from each other
3. They have empty space between them.

Front 20

14. Define freezing.

Back 20

14. It is the change of state from a liquid to a solid.

Front 21

15. Of the five changes of state, which are exothermic changes?

Back 21

15. Condensation and freezing

Front 22

10.Give 3 properties that describe plasmas.

Back 22

#10
1. Conduct electric current
2. Have magnetic fields
3. Can have a fixed or not fixed shape and volume

Front 23

11. True or False
Particles of a plasma have broken apart.

Back 23

11. True

Front 24

12. Give an example of something that contains plasma.

Back 24

12. A flourescent light

Front 25

7. What does Boyle's Law say?

Back 25

7. It states that for a fixed amount of gas at a constant temperature, volume decreases as pressure increases (or vice versa).

Front 26

8. What changes of state are endothermic?

Back 26

#8
1. Melting
2. Vaporization
3. Sublimation

Front 27

9. Define sublimation.

Back 27

9. It is the change in state from a solid directly into a gas.

Front 28

4. What state is 99% of known matter?

Back 28

4. Plasma

Front 29

5. What do you add or remove from water to get it to change state?

Back 29

5. Energy (Heat)

Front 30

6. List two differences between gases and plasmas. (Short Answer)

Back 30

#6
1. Plasmas conduct electricity and have magnetic fields. Gases do not.

Front 31

1. Classify each substance according to its state of matter: ice, apple juice, slice of bread, helium in a balloon, air, water, a textbook, and steam. (Short Answer)

Back 31

#1
1. SOLIDS: ice, slice of bread, textbook
2. LIQUIDS: apple juice, water
3. GAS: helium in a balloon, steam

Front 32

2. Describe how the motion and arrangement of particles change as a substance freezes. (Short Answer)

Back 32

2. MOTION: The motion will begin to slow down as it freezes.
ARRANGEMENT: The particles will start to get closer and closer until they can barely move.

Front 33

3. Give an example of a substance that undergoes the process of sublimation.

Back 33

3. Dry Ice
