METHOD - 1. Collect enough ice so that your beaker is half full and place the thermometer into it while you set up the rest of the equipment
2. Set up the retort stand and clamp alongside the the tripos and the gauze mat
3. place the beaker of ice on the gauze mat and gently clamp the thermometer so that it is held upright and the scale is easy to see. The bottom of your thermometer should be low Enough to still be covered with water when the ice melts, but not touching the the bottom of your beaker
4. record the initial temperature of the ice
5.light the Bunsen burner and start timing with the stopwatch
6. measure and record the temperature every minute
7. Continue measuring and recording the temperature until the water has been boiling for 2-3 minutes

DISCUSSION - We heated up the solid with the Bunsen burner, the temperature was 0. Eventually the solid turned into a liquid. Then after a while the liquid evaporated in to a gas in which the temp is 100 in Celsius.
