STATES OF MATTER AND CHANGES OF STATE SOLID

STATES OF MATTER AND CHANGES OF STATE

SOLID, LIQUID AND GAS

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

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

• 1. PARTICLE SPACING IS VERY FAR APART GAS • 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

CHANGES OF STATE OF MATTER

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

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

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

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

COMPARISON OF BOILING AND EVAPORATION

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

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

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

WATER FREEZING ALMOST IMMEDIATELY

THE LOWEST TEMPERATURE THAT IT IS POSSIBLE TO REACH (O⁰K, -273. 15⁰C, -459. 67⁰F) IS CALLED ABSOLUTE ZERO

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

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