Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional


to the difference between its own temperature and the ambient temperature (i.e. the temperature of


its surroundings).


Newton's Law of Cooling models the cooling (or heating) of an object which is placed in a surrounding medium (for example, a hot pizza that is taken out of the oven and allowed to cool on the kitchen counter). The formula is


                   u(x) = T + (I - T)eKx , (K < 0)

              

where u(x) represents the temperature of the object at time x, I is the initial temperature of the object, and T is the temperature of the surrounding medium. k is a cooling rate determined by the physical nature of the object, the container holding the object, etc.
