Water exists in three states of matter that
            are known as solid, liquid, and gas.

            Water in the solid state is known as ice.
            Water in the liquid state is known as water.            ice              water vapour
            Water in the gas state is known as water vapour.                 water

               AIM       To investigate the three states of matter of water.

               APPARATUS AND              Crucible, Bunsen burner, tripod stand, wire gauze,
               MATERIALS                  stopwatch, and ice cubes.


               STEPS













            1.  Place an ice cube in the crucible.       2.  Prepare the apparatus as shown
                Record the state of matter of the           in the picture.
                ice.
             3.  Start the stopwatch and heat the        4.  Continue heating until the water is
                crucible containing the ice cube            almost dried up. Turn off the Bunsen
                for two minutes. Then, observe              burner.
                the changes.
                                                             Be careful when handling
             5.  Record your observations in the             the Bunsen burner.
                table as shown below.

                                                    (a)  What are the changes in the states of
              Step 1                                    matter of the water that can be observed?
              Step 3                                (b)  What can you summarise from the
              Step 4
                                                        above activity?
                                                    (c)  Name the three states of matter of water.
