ATOMS ATOMS ARE THE BASIC BUILDING BLOCKS OF MATTER ATOMS ARE OFTEN FOUND LINKED TOGETHER RATHER THAN BEING SEPARATE LINKED ATOMS ARE CALLED MOLECULES

How Does Matter Change from One State to Another? Lesson 2 How Does Matter Change from One State to Another?

Lesson 2 Three States of Matter

Lesson 2 SOLID

PROPERTIES OF A SOLID HAS DEFINITE SHAPE HAS DEFINITE VOLUME FEELS FIRM PARTICLES ARE PACKED TIGHTLY TOGETHER LITTLE SPACE BETWEEN PARTICLES PARTICLES MOVE EXTREMELY SLOW

Lesson 2 LIQUID

PROPERTIES OF A LIQUID PARTICLES NOT PACKED TOGETHER TIGHTLY PARTICLES MOVE FREELY PARTICLES WILL TAKE THE SHAPE OF THE CONTAINER LIQUID EASILY CHANGES SHAPE

Lesson 2 GAS (VAPOR)

PROPERTIES OF A GAS (VAPOR) PARTICLES ARE FARTHEST APART PARTICLES MOVE VERY FAST PARTICLES TAKE SHAPE OF ANY CONTAINER DENSITY IS VERY LOW HIGH PRESSURE WILL TURN GAS INTO LIQUID

CHANGES BETWEEN STATES FREEZING MELTING BOILING CONDENSING

FREEZING HEAT IS REMOVED FROM A LIQUID PARTICLES SLOW DOWN AND MOVE CLOSER TOGETHER PARTICLES BECOME TIGHTLY PACKED TO FORM A SOLID

MELTING HEAT IS ADDED TO THE LIQUID PARTICLES BEGIN TO MOVE FASTER

BOILING LOTS OF HEAT IS ADDED HEAT GIVE THE PARTICLES ENOUGH ENERGY TO ESCAPE FROM LIQUID PARTICLES MOVE VERY FAST

CONDENSING THE REMOVAL OF HEAT FROM GAS PARTICLES SLOW DOWN AND MOVE CLOSER TOGETHER FROMING LIQUID

EVAPORATION OCCURS WHEN PARTICLES ESCAPE FROM A NONBOILING LIQUID AND BECOME A GAS

CONDENSATION WATER VAPOR IN THE AIR IS COOLED HEAT IS REMOVED FROM PARTICLES PARTICLES SLOW DOWN

SUBLIMATION PARTICLES ESCAPE FROM THE SURFACE AND BECOME A GAS SUBLIMATION IS A CHANGE IN STATE FROM A SOLID TO A GAS

ADDING HEAT AND TAKING HEAT AWAY CAUSES MATTER TO CHANGE STATES ADDING HEAT MAKES THE PARTICLES IN MATTER MOVE FASTER TAKING HEAT AWAY MAKES THE PARTICLES SLOW DOWN

FREEZING POINT EVERY SUBSTANCE HAS ITS OWN TEMPERATURE AT WHICH IT CHANGES FROM A LIQUID TO A SOLID

BOILING POINT THE TEMPERATURE AT WHICH A SUBSTANCE CHANGES FROM A LIQUID TO A GAS

MELTING POINT THE TEMPERATURE AT WHICH A SUBSTANCE MELTS AND FREEZES IS THE SAME THE MELTING POINT AND THE FREEZING POINT OF A SUBSTANCE ARE THE SAME

CHANGES IN MATTER PHYSICAL AND CHEMICAL CHANGES

Chemical Changes in Matter Q:What is chemical change? A: Changes that form different kinds of matter. EXAMPLES: in chemical changes the particles in the matter change. Flour, eggs, milk, and oil make pancakes.
