NEWTON'S LAW OF COOLING

1. What is the Newton’s Law of Cooling?
It is a method used in Forensic Science, which calculates the time of death of a body by calculating the difference between the temperature of the body and the temperature of the environment, if this last is constant.

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?

Temperature of the body = y
Temperature of the environment = yt
A Variable (to be determined)= k
A constant = C

3. According to this Law, at what time approximately the death happened?

7:26 pm

4. How does the room temperature affect the time of death?

Because after the body dies, the temperature of the body starts decreasing until it gets the same temperature as the one in the environment. This way, we can determine the time of death of the body.

5. How does an illness (e.g. fever) affect the time of death?

Because to calculate the time of death of the body, the temperatur of it must be constant, at least at time 0, as well as the one of the environment, so if the body was ill before the time of death, we cannot determined the temperature ot had before it died.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?

It is not perfectly exact, since the temperature of the environment must be exactly constant, as well as the temperature of the body before the time of death, but even though it is very difficult to know exact, it is very useful as a guide.
