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

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

GAS 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

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 POINTSMELTED GOLD

HEAT ENERGY ADDED TO A LIQUID EVAPORATION OR BOILING 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

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 (O ⁰K, ⁰C, ⁰F) IS CALLED ABSOLUTE ZERO

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

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