chapter 3 states of matter
section 3.1 solids, liquids, and gases (pages 68 - 74)
this section explains how materials are classified as solids, liquids, or gases. it also describes the behavior of these three states of matter.
reading strategy (page 68)
comparing and contrasting as you read about the states of matter, fill in the blanks in the diagram below with one of these phrases: definite volume, variable volume, or variable shape. for more information on this reading strategy, see the reading and study skills in the skills and reference handbook at the end of your textbook.
solid liquid gas
definite shape
describing the states of matter (pages 68 - 70)

1. what are three common states of matter?

a. solids b. ____________ c. ____________

1. is the following sentence true or false? the fact that a copper wire can be bent shows that some solids do not have a definite shape. ______________
2. circle the letter of each phrase that describes how particles at the atomic level are arranged within most solids.

a. randomly arranged
b. packed close together
c. arranged in a regular pattern

1. is the following sentence true or false? a liquid takes the shape of its container. ______________
2. is the following sentence true or false? a gas takes the shape and volume of its container. ______________
3. on the sun, where temperatures are extremely high, matter exists in a state known as ______________. circle the correct answer.

plasma liquid condensation

Explanation:

Step1: Recall common states of matter

The three common states are solids, liquids, and gases.

Step2: Analyze solid - shape property

A copper wire can be bent because it is malleable, but solids in general have a definite shape at the macroscopic level. So the statement is false.

Step3: Understand solid - particle arrangement

At the atomic level, particles in most solids are packed close together and arranged in a regular pattern.

Step4: Consider liquid property

Liquids take the shape of their container, so the statement is true.

Step5: Consider gas property

Gases take the shape and volume of their container, so the statement is true.

Step6: Recall high - temperature state of matter

At extremely high temperatures like on the sun, matter exists as plasma.

Answer:

1. b. Liquids; c. Gases
2. False
3. b. packed close together; c. arranged in a regular pattern
4. True
5. True
6. plasma
