RESEARCH QUESTION H ow does the rate of cooling of hot water depend on the thermal conductivity of the selected insulating materials ? INTRODUCTION Insulators are materials that inhibit the property of resisting electricity and heat. The idea of insulators sparked in my mind while referring a journal which discusses why a person feels warm even while wearing a light weight cloth. This discussion was based on the concept of heat transfer. In the chapter thermal physics, I remember the concept of heat transfer being discussed . My teacher introduced a concept called thermal conductivity to give more clarity and understanding about heat transfer. I decided to choose this topic because the concept of thermal insulation is very much used in our daily life. The cloths we wear, the buildings that are built, the mechanical systems that are manufactured, in automobiles, in electrical systems, mostly everywhere we see the application of thermal insulation. This sparked a cur...
