To solve the worksheet on "States of Matter," let's carefully analyze each question and fill in the blanks based on the properties of solids, liquids, and gases.
Key Properties of the States of Matter:
1.
Solid:
- Fixed shape and volume.
- Particles are closely packed and held together in an organized structure.
- Particles vibrate but do not move freely.
2.
Liquid:
- Takes the shape of its container but has a fixed volume.
- Particles are close together but can move past one another.
- Particles have more freedom to move than in solids.
3.
Gas:
- No fixed shape or volume; takes the shape and volume of its container.
- Particles are far apart and move freely in all directions.
- Particles are well-separated and collide with each other and container walls.
Filling in the Blanks:
1.
Everything we drink is in its ________ form.
- Drinks are typically liquids.
-
Answer: liquid
2.
________ takes on the shape of its container.
- Liquids take the shape of their container but maintain a fixed volume.
-
Answer: Liquid
3.
In the liquid state, particles are ________ and can move freely.
- In liquids, particles are close together but can slide past each other.
-
Answer: close together
4.
Matter in its ________ is characterized by having a fixed shape and volume.
- Solids have a fixed shape and volume.
-
Answer: solid state
5.
Particles in the ________ state are held together in an organized structure.
- In solids, particles are held together in a rigid, organized structure.
-
Answer: solid
6.

-
Answer: gas
8.
Particles are well separated and can move freely in the ________ state.
- In gases, particles are far apart and move freely.
-
Answer: gas
9.
Matter exists in ______ states: ________, ________, and ________.

-
Answer: 3, solid, liquid, gas
10.
________ matter doesn't have a fixed shape or volume.
- Gases do not have a fixed shape or volume.
-
Answer: Gas
Final Answers:
1. liquid
2. Liquid
3. close together
4. solid state
5. solid
6. gas
7. gas
8. gas
9. 3, solid, liquid, gas
