Insulation

Keeping things warm Aim: To find out which of these four materials is a better insulator to water under the same conditions for 5mins the materials are Bubble wrap, Aluminium foil, Cotton wool and Tissue paper. Prediction: I predict that Bubble wrap or cotton wool will be the best insulators due to the fact that they are thicker materials. Bubble wrap also has thick holes, which will trap the heat, but cotton wool is the …

…experiment were differnet to those that I had predicted. I had predicted that the best two insulators would probably be Cottton wool and Bubble Wrap. The finsihing temperature for all three materials were: Bubble Wrap 48c, Tissue paper 63, Aluminium Foil 64 and Cotton Wool 68. The worst insulator was what I had predicted to be the best. I can safely that Convection and Conduction took place in this experiment and they were major factors in this experiment.
