Investigating sate changes

Aim-to observe water as it changes sate from solid to liquid and then to a gas.

Method-

1-collect enough ice so that your beaker is half full and place the thermometer 

into it while you step up and rest of the equipment.

2-set up the retorts stand and clamp alongside the tripod and 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 by water when melts,but not touching the bottom of the beaker.

4-record the initial temperature of the ice in the data table.

5-light your 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 2-3 minutes.   

Discussion-the solid was melting into a liquid slowly.we were measuring the solid threw the thermometer.the water was evaporating and giving the measurement.
