Understanding States of Matter and Changes in State

Explore the characteristics of solids, liquids, and gases, along with their particle arrangements and movements. Learn how heat energy influences changes in states of matter such as melting, evaporation, boiling, and sublimation. Discover the importance of adding or subtracting heat energy to transition between different states of matter.

Presentation Transcript

1. STATES OF MATTER AND CHANGES OF STATE

2. SOLID, LIQUID AND GAS

3. 1. PARTICLES ARE TIGHTLY ARRANGED. NO SPACE BETWEEN ATOMS SOLID 2. DEFINITE SHAPE 3. DEFINITE VOLUME 4. PARTICLES VIBRATE NEXT TO EACH OTHER

4. 1. PARTICLES HAVE SOME SPACE BETWEEN. 2. DEFINITE VOLUME LIQUID 3. NO DEFINITE SHAPE 4. PARTICLE MOVEMENT IS A SLIDING ACTION PAST EACH OTHER

5. 1.PARTICLE SPACING IS VERY FAR APART 2. NO DEFINITE SHAPE 3. NO DEFINITE VOLUME 4. PARTICLE MOVEMENT IS VERY FAST AND MAY OR MAY NOT COME IN CONTACT WITH EACH OTHER GAS

6. CHANGES OF STATE OF MATTER

7. IN ORDER FOR A SOLID, LIQUID OR GAS TO CHANGE ITS STATE OF MATTER HEAT ENERGY IS EITHER ADDED OR SUBTRACTED

8. HOW DOES A SOLID, LIQUID OR GAS CHANGE ITS STATE HEAT ENERGY HAS TO BE ADDED OR SUBTRACTED

9. HEAT ENERGY ADDED TO A SOLID-MELTING OCCURS KITCHEN MELTING POINTS 97 F/16 C MELTED GOLD

10. HEAT ENERGY ADDED TO A LIQUID EVAPORATION OR BOILING WATER EVAPORATING MOLECULE MOTION IN EVAPORATION AND BOILING BOILING WATER

11. COMPARISON OF BOILING AND EVAPORATION

12. SUBLIMATION A SOLID CHANGES INTO A GAS WITHOUT BECOMING A LIQUID FIRST DRY ICE SNOW SUBLIMATION DRY ICE

13. WHEN HEAT ENERGY IS REMOVED A GAS BECOMES A LIQUID CONDENSATION WATER VAPOR CONDENSING ON SODA LITER WATER VAPOR CONDENSING ON GLASS WATER VAPOR CONDENSING ON PLANTS

14. REMOVAL OF HEAT ENERGY FROM A LIQUID FREEZING THERE IS A SPECIFIC TEMP AT WHICH LIQUIDS FREEZE

15. WATER FREEZING ALMOST IMMEDIATELY

16. THE LOWEST TEMPERATURE THAT IT IS POSSIBLE TO REACH (O K, -273.15 C, -459.67 F) IS CALLED ABSOLUTE ZERO

17. DEPOSITION WHEN HEAT ENERGY IS REMOVED AND WATER VAPOR CHANGES DIRECTLY INTO A SOLID FROST SNOW FROST

18. WATER HAS A FREEZING POINT OF 0C AND A MELTING POINT OF 0 C HOW IS THIS POSSIBLE???
