Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube, shiny foil can be used because it's a poor emitter of radiation and it will reflect escaping heat by reflecting, because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its …showed first 75 words of 3063 total…

The best part of the experiment for me was that all the results were collected and that they were accurate and reliable enough to give us a better picture of insulation. I don't think I would improve the experiment because it was simple and easier enough to do in a short amount of time. But I reckon we have had enough time so we enough time to get reliable and accurate results.
