Insulation PPT

  1. 1. By : Charlotte Griffin Class G5R February 2012
  2. 2. To test the difference in insulating propertiesbetween different materials by seeing how wellthey each stop a bottle of hot water fromcooling down over time.
  3. 3. I will use four materials in this experiment: tinfoil, a plastic bag, newspaper and a woollensock.I think that the woollen sock will keep thewater warmer for longer than all the othermaterials.
  4. 4.  Four identical plastic bottles Newspaper One woollen sock Tinfoil One plastic bag Thermometer Hot water Timer
  5. 5. 1.Wrap each plastic bottle in one of the four materials: tinfoil, a plastic bag, newspaper and a woollen sock.2.Pour an equal amount of hot water into the four insulated bottles.3.Take the temperature of the water in each bottle and record the data for Time Zero. Put the caps back on the bottles.4. Record the temperatures in the four bottles again after 5, 10, 20 and 30 minutes, keeping the caps on inbetween measurements.
  6. 6. 1. The temperatures in all four bottles decrease over time as the water starts off much hotter than room temperature.2. After only 5 minutes it was not so easy to tell the difference between the four bottles but the results were clearer after 30 minutes.3. There was a notable difference in temperature of 4 Degrees Centigrade between the bottles with the best insulating material and the worst after 30 minutes.

  8. 8. In this experiment, you can see that watercools at different rates when using differentmaterials for insulation.My hypothesis was correct, the woollensock did keep the water warmer than the othermaterials. The newspaper was the poorestinsulator.
  9. 9. Different materials have different insulatingcharacteristics, some are better than others atkeeping heat in or out.
