1.
Which state of matter has a definite shape and volume? (Multiple choice)
  1. Solid
  2. Gas
  3. Plasma
  4. Liquid
Show answer

Solid

Solids have a fixed shape and volume because their particles are tightly packed.
2.
What happens to particles in a liquid when it is heated? (Multiple choice)
  1. They freeze
  2. They move faster and spread out
  3. They become tightly packed
  4. They stop moving
Show answer

They move faster and spread out

Heating a liquid makes its particles move faster and spread apart.
3.
Which state of matter takes the shape of its container but has a fixed volume? (Multiple choice)
  1. Gas
  2. Solid
  3. Liquid
  4. Plasma
Show answer

Liquid

Liquids flow to take the shape of their container but keep their volume.
4.
What is the process called when a solid changes directly into a gas? (Multiple choice)
  1. Freezing
  2. Condensation
  3. Sublimation
  4. Melting
Show answer

Sublimation

Sublimation is when a solid turns directly into a gas without becoming liquid first.
5.
Gases have a definite volume but no definite shape. (True or false)
  1. True
  2. False
Show answer

False

Gases have neither definite shape nor definite volume.
6.
Plasma is a state of matter similar to gas but with charged particles. (True or false)
  1. True
  2. False
Show answer

True

Plasma consists of charged particles and behaves like an ionized gas.
7.
Name the state of matter that has particles packed very tightly and vibrate in place. (Identification)
Show answer

Solid

Solids have tightly packed particles that only vibrate in place.
8.
When a liquid changes into a gas, the process is called _____ . (Fill in the blank)
Show answer

evaporation

Evaporation is the change from liquid to gas.
9.
Match each state of matter with its description. (Matching type)
1. Solid
A. Takes shape of container but has fixed volume
2. Liquid
B. Has a fixed shape and volume
3. Gas
C. Fills the container and has no fixed shape or volume
4. Plasma
D. Ionized gas with charged particles
Show answer

1 = Has a fixed shape and volume; 2 = Takes shape of container but has fixed volume; 3 = Fills the container and has no fixed shape or volume; 4 = Ionized gas with charged particles

Each state of matter has unique properties.
10.
Give three examples of solids. (Enumeration)
Show answer

Ice, Wood, Rock

Ice, wood, and rock are all solids because they have fixed shape and volume.
