1. What is the Newton’s Law of Cooling?

It is a "satisfactory" approximation to the surface temperature of an object changes at a rate proportional to its relative temperature. That is, the difference between its temperature and the temperature of the surrounding enviroment.

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

The variables of time, and temperature of the body and the surrounding.

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

-With a room temperature at 70°F

1) Healthy/98.7°F - Time Of Death: 8:54:4 P.M.

2) Regular/99.5°F - Time Of Death: 8:50:4 P.M.

3)Sick/101°F - Time Of Death: 8:43:4 P.M.

-With a room temperature at75°F,

1) Healthy/98.7°F - Time of Death: 8:55:7 P.M.

2) Regular/99.5°F - Time of Death: 8:51:2 P.M.

3) Sick/101°F - Time of Death: 8:42:4 P.M.

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

Acording to the law of cooling, the room temperature affects the body because ther is a difference between the temperatures of the body and the room and this makes that the both temperatures make an equilibrium by staying in touch one with another.

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

An illness shall change the temperature of the body because all the reactions that the illnes produces.

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

It is satisfactory approximate
