					                       STATES OF MATTER

Q1. Draw the particles of the 3 states of matter in the boxes on the
left below.

                             SOLIDS
                         Particles held closely together
                         Attractive forces are very strong between
                          particles
                         Particles vibrate


                  MELTING                  FREEZING
                            LIQUIDS
                         Particles not held as strongly together as in
                          solids
                         Attractive forces not as strong as in solids
                         Particles are moving but much more slowly
                          than in gases

             EVAPORATION                   CONDENSATION
                             GASES
                         Particles are far apart
                         Attractive forces between particles are
                          weak
                         Particles move quickly


Q2. Write definitions (with correct sentence structure) for each of
the following terms:
 Solid -


 Liquid –


 Gas –


 Melting –

 Freezing or Solidification –
 Boiling or Evaporation –

 Condensation –

 Sublimation –

 Melting Point –

 Boiling Point –


Q3. Complete the table below:

 CHEMICAL           MELTING      BOILING   STATE AT ROOM
   NAME             POINT (oC)    POINT    TEMPERATURE

Helium                 -272        -269
Hydrogen               -259        -252
Oxygen                 -218        -183
Nitrogen               -210        -195
Ethanol                -114         79
(Alcohol)
Water                  0           100
Common Salt           804          808
Copper                1083        2567
Iron                  1535        2750
Tungsten              3410        5660
