STATES OF MATTER
THE PHYSICAL FORMS OF MATTER THAT INCLUDE SOLID, LIQUID, AND GAS.

3. SOLID
THE STATE OF MATTER WHERE THE VOLUME AND SHAPE OF A SUBSTANCE IS FIXED.

4. LIQUID
THE STATE OF MATTER WHERE THE VOLUME HAS DEFINITE VOLUME BUT DOES NOT HAVE A DEFINITE SHAPE. TAKES THE SHAPE OF ITS CONTAINER.

5. GAS
A FORM OF MATTER THAT DOES NOT HAVE A DEFINITE VOLUME OR SHAPE

6. CHANGE OF STATE
THE CHANGE OF A SUBSTANCE FROM ONE PHYSICAL FORM TO ANOTHER

7. TEMPERATURE
A MEASURE OF THE AVERAGE KINETIC ENERGY IN AN OBJECT HOW HOT OR COLD SOMETHING IS

8. THERMAL EXPANSION
AN INCREASE IN THE SIZE OF A SUBSTANCE IN RESPONSE TO A CHANGE IN TEMPERATURE

9. ABSOLUTE ZERO
THE TEMPERATURE WHERE ALL MOLECULAR MOTION STOPS

10. MELTING
THE CHANGE OF STATE IN WHICH A SOLID BECOMES LIQUID BY ADDING ENERGY

11. FREEZING
THE CHANGE OF STATE FROM A LIQUID TO A SOLID BY REMOVING ENERGY

12. EVAPORATION THE CHANGE OF A SUBSTANCE FROM A LIQUID TO A GAS
BY ADDING ENERGY
HAPPENS ON THE SURFACE OF A LIQUID

13. BOILING THE CHANGE OF STATE FROM A LIQUID TO A GAS BY ADDING ENERGY
HAPPENS BELOW THE SURFACE OF A LIQUID

14. CONDENSATION THE CHANGE OF STATE FROM A GAS TO A LIQUID
BY REMOVING ENERGY

15. SUBLIMATION
THE CHANGE OF STATE WHERE A SOLID TURNS DIRECTLY INTO A GAS BY ADDING ENERGY EXAMPLE- DRY ICE
