Changing states

• System gains more energy = change in temperature / change in state

  system heated enough = enough energy to break bonds
• Changes state = no chemical change, only physical

  -number of particles doesn’t change

  -mass is conserved
• 1 ) evaporation

  2 ) melting

  3 ) condensation

  4 ) freezing

  5 ) solid

  6 ) liquid

  7) gas

  8 ) sublimation
