describing the states of matter

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:

Identify states of matter

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

$$ \text{a. Solids, b. Liquids, c. Gases} $$

Evaluate solid properties

A copper wire being bent is a physical change of shape, but the solid copper still maintains a definite shape unless acted upon by an external force. The statement "The fact that a copper wire can be bent shows that some solids do not have a definite shape" is false.

$$ \text{Answer: false} $$

Analyze particle arrangement in solids

Particles in most solids are packed close together and arranged in a regular, repeating pattern.

$$ \text{Correct options: b, c} $$

Evaluate liquid and gas properties

A liquid takes the shape of its container (true). A gas takes both the shape and volume of its container (true).

$$ \text{4. true, 5. true} $$

Identify high-temperature state of matter

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

$$ \text{Answer: plasma} $$
