The purpose of this investigation was to explore the rate of cooling of the coffee cups in different materials, with and without milk during a 45-minute interval. This practical analysed the rate of cooling reduces consistently or whether it slows as the temperature falls. In this job, four cups made of materials ceramic and plastic and paper were utilised, in which only a ceramic mug and plastic contained milk. This was done to see whether the components and the kind of cup had a role in slowing down the temperature and vice versa. It was necessary to evaluate the room temperature before beginning the experiment since it was a factor in chilling the coffee. To make this work, four thermometers were used to measure the temperature of the room as well as the temperature of each cup. To record the data, within a spreadsheet, every minute, the temperature of the coffee is to be recorded.
