Question

in your textbook, read about states of matter. label each drawing with one of these words: solid, liquid, gas. 18. drawing of particles in a box with some space between them 19. drawing of closely - packed particles in a box 20. drawing of particles filling the box for each statement below, write true or false. 21. all matter that we encounter in everyday life exists in one of three physical forms. 22. a solid has definite shape and volume. 23. a liquid has a definite shape and takes on the volume of its container. 24. a gas has both the shape and the volume of its container. 25. the particles in a gas cannot be compressed into a smaller volume. 26. liquids tend to contract when heated. 27. the particles in a solid are spaced far apart. 28. the words gas and vapor can be used interchangeably.

Explanation:

Step1: Analyze particle arrangement in 18

Particles are spread out and fill the container, typical of gas.

Step2: Analyze particle arrangement in 19

Particles are closely - packed in an orderly pattern, typical of solid.

Step3: Analyze particle arrangement in 20

Particles are closely - packed but can move past each other, typical of liquid.

Step4: Evaluate statement 21

All matter in everyday life exists in one of three states (solid, liquid, gas), so it's true.

Step5: Evaluate statement 22

A solid has definite shape and volume, so it's true.

Step6: Evaluate statement 23

A liquid has no definite shape and takes the shape of its container, so it's false.

Step7: Evaluate statement 24

A gas takes the shape and volume of its container, so it's true.

Step8: Evaluate statement 25

Gas particles can be compressed, so it's false.

Step9: Evaluate statement 26

Liquids expand when heated, so it's false.

Step10: Evaluate statement 27

Solid particles are closely packed, not far apart, so it's false.

Step11: Evaluate statement 28

Gas and vapor are not always interchangeable, so it's false.

Answer:

1. gas
2. solid
3. liquid
4. true
5. true
6. false
7. true
8. false
9. false
10. false
11. false
