|
THE PARTICLES WOULD BE CLOSE TOGETHER BUT NOT IN NEAT ROWS
|
|
|
WHAT DOES THE DIAGRAM OF PARTICLES FOR A GAS LOOK LIKE?
|
THE PARTICLES WOULD BE FAR APART AND BECAUSE THEY MOVE FAST THERE WILL BE AN ARROW ON EACH PARTICLE POINTING IN A DIFFERENT DIRECTION
|
|
|
WHAT IS THE DENSITY OF A SUBSTANCE DEFINED AS?
|
MASS / VOLUME
|
|
|
WHAT IS DENSITY?
|
DENSITY IS THE MASS OF A 1CM CUBED OF A SUBSTANCE

|
UNITS CALLED GRAMS PER CENTIMETRE CUBED G/CM3

|
ITS MASS IN GRAMS AND ITS VOLUME IN CM3
|
|
|
WHAT IS THE EQUATION OF DENSITY?
|
DENSITY(G/CM3) = MASS (G)
VOLUME (CM3) |
|
|
WHAT DO DENSER SUBSTANCES HAVE?
|
MORE PARTICLES IN THE SAME VOLUME
|
|
|
WHAT DENSITY DO SOLIDS LIQUIDS AND GASES HAVE IN GENERAL?
|
SOLIDS = HIGH DENSITY
LIQUIDS = FAIRLY HIGH GASES = VERY LOW DENSITY |
|
|
WHAT IS GAS PRESSURE CAUSED BY?
|
PARTICLES COLLIDING WITH THE SIDES OF THE CONTAINER
|
|
|
WHAT IS DIFFUSION?
|
DIFFUSION IS THE 'SPREADING OUT' OF A LIQUID OR GAS AND OCCURS DUE TO RANDOM MOVEMENTS OF THEIR PARTICLE
|
|
|
WHAT DOES SOLUBLE MEAN?
|
SUBSTANCES WHICH WILL DISSOLVE ARE CALLED SOLUBLE
|
|
|
WHAT DOES INSOLUBLE MEAN?
|
SUBSTANCES WHICH WILL NOT DISSOLVE ARE CALLED INSOLUBLE
|
|
|
WHAT DOES SOLUTE MEAN?
|
THE SOLID THAT IS BEING DISOLVED IS CALLED THE SOLUTE
|
|
|
WHAT DOES SOLVENT MEAN?
|
THE LIQUID WE ARE DISSOLVING THE SOLID IN, IS CALLED THE SOLVENT
|
|
|
WHAT DOES SOLUTION MEAN?
|
WHEN A SOLID DISSOLVES IN A LIQUID, WE SAY THAT A SOLUTION IS MADE
|
|
|
SOLUBILITY INCREASES WITH WHAT?
|
TEMPERATURE
|
|
|
WHAT DOES A SATURATED SOLUTION CONTAIN?
|
IT CONTAINS THE MAXIMUM AMOUNT OF DISSOLVED SUBSTANCE
|
|
|
WHAT IS THE TEST WHEN COBALT CHLORIDE PAPER CHANGES FROM BLUE TO PINK?
|
A TEST FOR WATER
|
|
|
WHAT DO SOLIDS, LIQUIDS AND GASES DO WHEN THEY ARE HEATED?
|
THEY EXPAND
|
|
|
THE IRON BALL CAN FIT THROUGH THE LOOP. AFTER HEATING IT UP WITH A BUNSEN BURNER, WHAT DID THE IRON BALL DO?
|
IT EXPANDED. THE BALL CANNOT FIT THROUGH THE LOOP ANY MORE
|
|
|
WHAT DO SOLIDS, LIQUIDS AND GASES DO WHEN THEY ARE COOLED?
|
THEY CONTRACT
|
|
|
THERE IS A TUBE STICKING OUT OF THE TOP OF A GLASS BALL. IT HAS GREEN LIQUID HALF WAY UP THE TUBE. WHAT WILL HAPPEN WHEN THE GLASS BALL IS HEATED?
|
THE GREEN LIQUID WILL EXPAND AND IT WILL COME OUT OF THE TOP OF THE TUBE
|
|
|
A GLASS BOTTLE HAS AIR IN IT WITH A TUBE COMING OUT OF THE TOP. A GLASS OF WATER IS PLACED UNDERNEATH SO THE TUBE CAN GO IN IT. WE HEATED UP THE GLASS BALL BY PLACING OUR HANDS AROUND IT. WHAT HAPPENED WHEN THE AIR GOT HEATED UP?
|
THE AIR EXPANDED AND CAME DOWN THE TUBE. THE AIR BLEW BUBBLES IN THE GLASS OF WATER UNDERNEATH IT
|
|
|
WHAT DOES A HORIZONTAL SECTION OF A HEATING CURVE SHOW?
|
A CHANGE OF STATE
|
|
|
WHAT DOEA AN IMPURITY DO IN A SUBSTANCE?
|
IT MAKES ITS MELTING POINT LOWER BUT ITS BOILING POINT HIGHER
|
|
|

|
HOW CAN WE USE DISTILLATION?
|
WE USE THIS TECHNIQUE TO SEPARATE A SOLUTION INTO THE SOLUTE (THE DISSOLVED SUBSTANCE AND THE SOLVENT (THE LIQUID IT IS DISSOLVED IN)

|
HOW DOES CHROMATOGRAPHY WORK?
|
1. DIFFERENT SUBSTANCES MOVE UP THE PAPER AT DIFFERENT SPEEDS
