Explorations with Newton's Law of Cooling
The rate at which an object cools is proportional to the difference between its temperature and that of its environment.
Adjust the initial temperature of the object (u0) and the constant temperature of the environment (T).
Also, indicate the temperature of the object (b) after the object has been cooling for (a) minutes.
Finally, observe that the ratio of the current rate of change of the temperature of the object to that of its original rate of change is equal to the ratio of the current difference between the temperature of the object and its environment and the original difference between the temperature of the object and its environment.
