Newton's Law of Cooling Applications

Click For Summary
SUMMARY

Newton's Law of Cooling has practical applications in various fields, including forensic science and thermodynamics. Key examples discussed include determining the time of death and cooling down food items like soup. A third example suggested involves measuring the cooling rate of an object to calculate its surface area by observing the time taken to reach ambient temperature. This method was successfully demonstrated in a classroom experiment, highlighting its educational value and practical relevance.

As part of my research, i have to find 3 pratical examples that Newtons Law of cooling can be used for. So far i have two, finding the time someone died, and cooling down soup. I have to find a third, which does not involve food, or someone dying. if anyone could suggest a good third practical example of this law it would be greatly appreciated, thanks.

By controlling the temperature of the object and the surroundings you could determine the surface area of the object by measuring how long it takes before the object has the same temperature as the surroundings.
 
HEY THAT WAS MINE! WE HAD TO DO THAT IN CLASS AS AN ExPERIMENT! THATS NOT FAIR.. I am glad though that someone else thought of it, my lab partners thought i was crazy.. but it worked and we got an A (98).
