1. The problem statement, all variables and given/known data Mathematically prove how Newton's Law of Cooling is derived. 2. Relevant equations Newton’s Law of Cooling states that the rate of change of a temperature of an object is directly proportional to the difference between its own temperature and the temperature of its surroundings (Smith, 2010). Therefore, from this information it can be seen that the following relationship can be interpreted. dT/dt ∝ T-Ts Where T = temperature of the object and t = time. 3. The attempt at a solution not sure how the k comes into it?
