States of matter

• solid

  • Regular
  • Fixed position
  • Vibrate about a fixed position
  • Low kinetic energy
• liquid

  • Random arrangement
  • Move past each other (touching)
  • Take shape of the container
  • Flow (Medium kinetic energy)
• gas

  • Move in random directions
  • Spread out in all directions
  • High kinetic energy
• • Solid to Gas ---> Sublimination
• • Gas to Solid ---> Deposition
• melting


  energy used to weaken intermolecular forces
• evaporating


  energy used to completely weaken intermolecular forces
• pure substance


  all of the same type of substance (1 type of element or compound)
• mixture


  A mixture is made up of one or more element or compound that are not chemically bonded
• Flat line of a graph = Pure Substance
• steps of portable water?

  1. screening= big mesh wire to sieve out big debris
  2. sedimentation= insoluble medium sized debris sink to bottom of tank
  3. filtration= small insoluble bits are filtered using iron sulfate
  4. chlorination= chlorine added to kill microbes
