2.  ANYTHING THAT TAKES UP SPACE AND HAS MASS STATE OF MATTER IS DETERMINED BY: THE MOTION OF THE PARTICLES AND THE STRENGTH OF ATTRACTION BETWEEN PARTICLES

3.  ATOMS  MOLECULES  IONS

4.  MATTER WITH A DEFINITE SHAPE  PARTICLES ARE PACKED CLOSELY TOGETHER AND VIBRATE IN PLACE.

5.  PARTICLES IN A REPEATING THREE DIMENSIONAL PATTERN

6.  PARTICLES ARE IN A RANDOM ARRANGEMENT  EXAMPLES: GLASS, RUBBER, PLASTIC

7.  THEY HAVE A DEFINITE VOLUME BUT NO DEFINITE SHAPE.  THE PARTICLES MOVE ABOUT MORE FREELY THAN SOLIDS.

8.  A LIQUIDS RESISTANCE TO FLOW.  THE SLOWER A LIQUID FLOWS THE HIGHER ITS VISCOSITY.  VISCOSITY INCREASES AS THE LIQUID GETS COLDER.

9.  PARTICLES ON THE SURFACE ARE PULLED TOGETHER TOWARD THE CENTER.

10.  PARTICLES DO NOT HAVE A DEFINITE SHAPE OR VOLUME.  THE PARTICLES MOVE OUT FARTHER THAN LIQUIDS AND SOLIDS. THEY MOVE AT HIGH SPEEDS IN ALL DIRECTIONS.

11.  SIMILAR TO A GAS  THE ATOMS OR MOLECULES HAVE IONIZED (THE NUMBER OF ELECTRONS HAS BEEN REDUCED OR INCREASED)

12.  THE TOTAL KINETIC AND POTENTIAL ENERGY IN A SAMPLE OF MATTER.

13.  THE AVERAGE KINETIC ENERGY OF THE INDIVIDUAL PARTICLES OF A SAMPLE OF MATTER.  HEAT – THE TRANSFER OF THERMAL ENERGY FROM A SUBSTANCE THAT HAS A HIGHER TEMPERATURE TO ONE WITH A LOWER TEMPERATURE.

14.  THE AMOUNT OF HEAT IT TAKES TO RAISE THE TEMPERATURE OF 1 G OF A SUBSTANCE 1 DEGREE CELSIUS.  MELTING- THE TEMPERATURE AT WHICH A SUBSTANCE CHANGES FROM SOLID TO A LIQUID.  FREEZING- THE CHANGE FROM A LIQUID TO A SOLID STATE.

15.  THE CHANGE OF A SUBSTANCE FROM A LIQUID TO A GAS STATE.  BOILING POINT – THE TEMPERATURE AT WHICH A LIQUID BOILS.  EVAPORATION- TAKES PLACE AT THE SURFACE OF A LIQUID AND CAN TAKE PLACE BELOW THE BOILING POINT.

16.  WHEN GAS COOLS DOWN AND CHANGES TO A LIQUID

17.  UNIT OF MEASURE FOR FORCE

18.  PRESSURE = FORCE AREA = NEWTONS AREA = _N_ m2

19.  THE DIFFERENCE IN PRESSURE RESULTS IN UPWARD FORCE ON AN OBJECT IN A FLUID.

20.  THE BOUYANT FORCE ON AN OBJECT IS EQUAL TO THE WEIGHT OF THE FLUID DISPLACED BY THE OBJECT.

21.  DENSITY = __ MASS__ VOLUME

22.  WHEN A FORCE IS APPLIED TO A CONFINED FLUID, AN INCREASE IN PRESSURE IS TRANSMITTED EQUALLY TO ALL PARTS OF THE FLUID.
