states of matter boiling points

• solids

  • thick structure
  • around a fixed point
  • vibration , not flowing , cannot be compressed
• liquid

  • movement around
  • not in a fixed position
  • can flow , cant be compressed
• gas

  • free to move
  • not around a fixed position
  • can flow , can be compressed
• solid to liquid = melting --

  liquid to gas = evapouration -- energy in

  gas to liquid - condensing --

  liquid to gas - freezing -- energy out
• melting point = freezinf point
• boil = liquid to gas
• liquid + liquid = solid ( cloudy )
• liquid +solid = gas

  liquid +liquid = gas ( bubbles / fizzing loss of mass
• (s) = solid

  (l) = liquid

  (aq)= aqueaus

  (g) = gas
• Boiling Point

  the point at which a substance turns into a liquid
• Identify BP on a graph

  Plateau
• Interparticle Forces

  Forces between molecules (particles)
• What is going on during the flat section of our boiling point graphs? (What is happening to particles & space between them when boiling?)

  It has reached its boiling/freezing point of can not reach temp to get there
• How could we determine in a lab that boiling point was a characteristic property?

  It helps defines substances
• What external factor affects boiling point?

  Energy (heat)
• How does a higher elevation affect boiling point?

  when the air pressure i s high so is the boiling point
• Barometer

  Device to measure air pressure
