Cooling curves - Temperature in insulators Preliminary Investigation Question Which of the four materials acts as the best insulator when wrapped around a glass beaker which is filled with boiling water? Aim The aim of this investigation is to test four materials (polystyrene, fibre glass, cotton wool and bubble wrap), to see which one acts as the best insulator. The temperature of the boiling water and the material inside and outside will be taken at regular intervals by a data logger and form this it will show the material that can insulate the best. So this chosen material can be further tested in the main practical by testing various thicknesses of the material, finding the optimum size at which the material acts best as the insulator. Theory In theory a good insulator and poor insulator will produce a graph like this: A good insulator will keep the temperature of the boiling water as high as possible during...
