1. The three main states of matter are solid, liquid, and gas.

2. The state of matter that has a definite shape and volume is a solid.

3. When a solid melts, its particles gain energy and begin to move more freely.

4. The state of matter that has neither a definite shape nor a definite volume is gas.

5. The process that changes a gas directly into a solid is called deposition.

6. Plasma is a state of matter where atoms are ionized and consists of charged particles (ions
and electrons). It is commonly found in stars, including the sun, and lightning.

7. The process that turns a liquid into a gas is called evaporation or boiling.

8. False: In gases, particles are far apart and move freely, not tightly packed and vibrating in
place.

9. One factor that can cause a change in the state of matter is temperature (heating or cooling).

10. Lightning is considered a form of plasma.

11. The state of matter where particles are far apart and move freely is gas.

12. The process that changes a solid into a liquid is called melting.

13. The main difference between a liquid and a gas is that liquids have a definite volume but no
definite shape, while gases have neither a definite shape nor a definite volume.

14. The state of matter with the most kinetic energy is gas.

15. When the temperature of a gas increases, its volume usually increases, according to
Charles' Law.

16. In a gas, particles move freely and rapidly, while in a liquid, particles move more slowly but
still slide past each other.
17. Sublimation is the process where a solid changes directly into a gas, bypassing the liquid
state. An example is dry ice (solid CO₂) turning into gas without becoming liquid.
18. The state of matter with a fixed volume but no fixed shape is a liquid.
19. Condensation is the process where a gas turns into a liquid. It is part of the water cycle,
where water vapor in the air cools and condenses to form clouds or liquid water.
20. Pressure can affect the state of matter, especially in gases. Increasing pressure usually
compresses gases, causing them to condense into liquids or solids if the pressure is high
enough.
