- Place the beaker on the gauze mat and gently clamp the thermometer so that it is held upright. The bottom of the thermometer should be low enough to be covered by the water but not toughing the bottom of the beaker.
- Record the temperature of the ice.
- Light the Bunsen Burner and start timing with your stopwatch.
- Record the temperature every 1 minute
- Keep recording until the water has been boiling for 1-2 minutes.
