Instructions to operate * Kettle to the boil * Pour 500ml of water in cup (plastic) * Place thermometer in water * Take temperature every minute for the 1st 30 mins and then every 5mins for the next 30 min and then every 10 mins until it is back to room temperature. * Experiment conducted 3 x (results averaged) * Used the exact same equipment for each experiment (water type, container, thermometer, kettle) My apparatus is designed to simulate the process of exponential decay. The model was measuring the temperature drop from boiling water. It was considered that the temperature would only ever drop to room temperature, therefore the temperature difference between the water temp and the room temp was measured to get a final reading of zero, which outlines Newton's cooling law. From experimental observations it is known that (up to a ``satisfactory'' approximation) the surface temperature of an object changes at a rate proportional to its...
