2. GASES FLOW EASILY
3. GASES CAN BE COMPRESSED EASILY
4. GASES HAVE A LOW DENSITY
5. PARTICLES ARE FAR APART
6. MOVE VERY QUICKLY
WHAT ARE SOLIDS, LIQUIDS AND GASES CALLED?
THE THREE STATES OF MATTER
ALL LIQUIDS AND GASES ARE MADE UP OF PARTICLES WHICH ARE ALWAYS MOVING. WHAT IS THIS CALLED?
THE PARTICLE THEORY OF MATTER
WHAT DOES THE DIAGRAM OF PARTICLES FOR A SOLID LOOK LIKE?
THE PARTICLES WOULD BE IN NICE STRAIGHT ROWS WITH NO SPACES
WHAT DOES THE DIAGRAM OF PARTICLES FOR A LIQUID LOOK LIKE?
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
WHAT DO WE MEASURE DENSITY IN?
UNITS CALLED GRAMS PER CENTIMETRE CUBED G/CM3
WHAT DO WE NEED TO KNOW ABOUT THE SUBSTANCE TO BE ABLE TO WORK OUT ITS DENSITY?
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 MANY DIFFERENT ELEMENTS ARE THERE?
100
WHAT IS AN ELEMENT
A SUBSTANCE THAT CONTAINS ONLY 1 TYPE OF ATOM IS CALLED AN ELEMENT
EVERYTHING IS MADE BY JOINING DIFFERENT TYPES OF WHAT TOGETHER?
ATOM
WHAT ARE ATOMS?
TINY BUILDING BLOCKS FROM WHICH EVERYTHING IS MADE
A SUBSTANCE WHICH CONTAINS MORE THAN 1 TYPE OF ATOM IS CALLED A WHAT?
A COMPOUND
APPROXIMATELY, HOW MANY DIFFERENT TYPES OF ATOM ARE THERE?
100
A LIST OF ELEMENTS IS CALLED THE WHAT?
THE PERIODIC TABLE OF ELEMENTS
WHAT DO ALL ELEMENTS HAVE?
A SYMBOL. EG - H = HYDROGEN
WHAT IS A COMPOUND?
A COMPOUND IS DIFFERENT TO AN ELEMENT AS IT CONTAINS 2 OR MORE TYPES OF ELEMENTS
WHAT IS AN ATOM?
AN ATOM MAKES UP EVERYTHING. IT IS ONLY 1 EG - H = HYDROGEN
WHAT IS AN ELEMENT?
AN ELEMENT IS SOMETHING WHICH ONLY CONTAINS THE SAME ATOM
WHAT IS A MOLECULE WHEN TALKING ABOUT ELEMENTS?
A MOLECULE IS A PARTICLE THAT CONTAINS 2 OR MORE ATOMS JOINED TOGETHER. A MOLECULE CAN BE A COMPOUND OR AN ELEMENT
WHAT IS A MIXTURE WHEN TALKING ABOUT ELEMENTS?
A MIXTURE IS MOST SUBSTANCES IN EVERY DAY LIFE. IT IS POSSIBLE TO SEPARATE MIXTURES INTO THE INDIVIDUAL SUBSTANCES THAT THEY CONTAIN
ATOMS IN A COMPOUND ARE STRONGLY WHAT TOGETHER BUT ARE NOT IN A MIXTURE?
BONDED
TRUE OR FALSE, MIXTURES CAN BE EASILY SEPARATED?
TRUE
HOW CAN YOU FILTRATE A MIXTURE?
BY MAKING A CONE OUT OF FILTER PAPER AND PLACING IT INTO A FUNNEL. TIP THE SOLUTION ONTO THE PAPER AND THEN THEY WILL SEPARATE
HOW CAN YOU EVEPORATE A MIXTURE?
1. YOU COULD BOIL IT
2. LEAVE IT IN THE SUN TILL THE LIQUID HAS GONE
3. IF THE LIQUID IS FLAMMABLE, PLACE IT OVER A HOT BATH
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
