Method

  • First place a small beaker placed inside a larger beaker
  • Then use a kettle to boil some water and transfer 80cm into the small beaker
  • Then use cardboard as a lid with a hole
  • Place thermometer through hole
  • Record starting temperature
  • Start a stopwatch
  • Record temperature every 3 minutes for 15 minutes
  • Repeat but use an insulating material to fill gap between beakers using same mass of material This practical could also be done with varying the amount of layers of insulation rather than the material
