The graph is an exponential curve and it shows that the temperature falls quickly at the beginning and then slowly as the difference of temperature goes on decreasing. Newton’s Law of Cooling states that the rate of change in temperature T of an object 3. Rather than use Newton’s law of cooling in this form, it is often helpful to examine the behavior of the temperature of an object as a function of time while it is cooling. This simple principle is relatively easy to prove, and the experiment has repeatable and reproducible results. 4.
