Newton's Law of Cooling Estimating!!!!?

Question

Mr. D has a cup of tea which is 80 degrees celcius and it takes 25 minutes for it to cool to room temperature (20 d. Celcius). Create a table of values to show the rate of cooling

Answer 1

According to Newton's Law, the rate of cooling is directly proportional to the temperature difference between the object and its surrounds. This is the same decay law as for a first order chemical reaction, or for radioactive decay, and the theoretical time for the process to go to completion is infinity.

So no wonder you have been waiting five hours for an answer. There isn't one.
