    •  
    • Diffusion of bromine gas Experiment diffusion of bromine in air The diffusion of bromine progresses Air colourless ______________________ spreads through the first cylinder
    • ___________________________ The reddish-brown vapor moves upward, slowly filling the ___________________ Reddish-brown vapour spreads through the __________________
    • Kinetic Theory of Matter The _________________ and _________________ of ______________________ in
    • KINETIC THEORY OF MATTER in SOLIDS
      • The particles are _________________________ in an _____________________
      • There are __________________ between the particles
      • The particles can only _________ and __________ in _________ positions
      A Solid has a _____________ and _____________ A Solid cannot be ________________
    • KINETIC THEORY OF MATTER in LIQUIDS A liquid has a ______________ but _______________ have a ________________. It takes the __________ of the container A liquid ___________________________________________________
      • The particles are _______________________ but ________ in ____________________________
      • The particles are held together by ___________________ but ______________________ than the forces in _____________
      • The particles can _________________________ against each other
    • KINETIC THEORY OF MATTER in GAS A gas ___________ have a __________ __________or ____________ A gas can be ____________________________
      • The particles are _________________ from each other and in a ___________________________
      • There are ______________ between the particles
      • The particles can ___________________________. The rate of _______________n is __________________ than in liquids
    • ________ More than in _______ but less than in _______ _________ _________ contents of the particles Low _________ _________ _________ GAS LIQUIDS SOLIDS Properties
    • CHANGES IN THE STATE OF MATTER
      • Matter may change their ________________ when there are changes in the _______________ and _____________
      • Example: _________
      • - ________ than __ 0 C  ______ state exist
      • - ____________than ____ 0 C  _________
      • state exist
      • - Between _________ 0 C  _______ state
      • exist
      • Matter of any state __________ heat energy when ___________ and __________ heat energy when __________
    • CHANGES IN THE STATE OF MATTER ___________________ ____________________ EVAPORATION or BOILING _____________________ _____________________
    • INTER-CONVERSION OF THE STATES OF MATTER
    • MELTING When a _________ is heated The particles in the solid __________________ _____________and _______________________ The particles vibrate faster as the __________ _________until the energy they gained is able to ____________________ that hold them at their _______________________ At this point the __________ becomes _________________ Process  _______________ HEAT SOLID LIQUID The temperature at this point: _______________
    • MELTING POINT
      • ________________ at which a ____________ changes into a __________ at a particular pressure
    • FREEZING When a __________ is _____________ The particles in the liquid ______________ __________and ______________________ As the _____________ continues to ________, the particles continue to _________________ until they do not enough energy to ___________________ At this point the _____________ changes into a ________________ Process  ________________ The temperature at this point: ______________________________
    • FREEZING POINT
      • _____________at which a ________ changes into a __________ at a particular pressure
      FREEZING LIQUID SOLID
    • CHANGE IN THE STATE OF MATTER IN NAPHTHALENE HEATING CURVE OF NAPHTALENE Melting point -------- A Solid B C Start to melt Melt completely D
    • At point ____, naphthalene exists as ___________ When _______ is heated, ______________ is absorbed that cause particles to _______________ and _____________ ( This is why temperature ______________ from point _____ to point _____) At point ___, solid naphthalene begins to __________ During the ____________, the temperature of naphthalene does not rise even though heating continues because heat energy ____________ by the particles is used to _____________ the ____________________ so that _______________ can turn into ___________
    • This constant temperature: ____________________ of Naphthalene Both ______________ and ___________ are present At point _____, ________________ naphthalene has ____________ From point _____ to point ______, the particles in liquid naphthalene absorb heat energy and move faster  ____________________
