Newton´s Law of Cooling

1. What is the 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

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?
a) The actual body temperature at the time of death; and
b) Post mortem temperature

3. According to this Law, at what time approximately the death happened?
Between 14 to 16 minutes before 9:10PM

4. How does the room temperature affect the time of death?
The death can decrease his temperature below the room temperature. Heavy clothing and other coverings, by retaining body heat, will speed up putrefaction. Rapid putrefactive changes may been seen in corpses left in a room which is well heated, or in a bed with an electric blanket.

5. How does an illness (e.g. fever) affect the time of death?
In the temperature, because he had more temperature and more heat, that also affect the time of death, while the temperature is going down.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?
They are common, because if we consider the variables in body’s heat, the reliability of algor mortis permits an approximation to the time of death. There are many facts that modify the results.
