1. What is the Newton’s Law of Cooling?
It's a method used to determine the time of death of a murder's victim by using the body temperature and the environment temperature.

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?
the temperature of the environment, the body and the time the temperature was taken.

3. According to this Law, at what time approximately the death happened?
Between 8:48 PM and 8:55 PM

4. How does the room temperature affect the time of death?
We have to be very precise when taking the temperature of both; the body and the environment, because with one small change in the environment an inocent person can be found guilty.

5. How does an illness (e.g. fever) affect the time of death?
Because it changes the body temperature.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?
It can be very accurate in most of the cases, but you need to have the correct information, because if the victim is sick or the environment is constantly changing this method won't be useful.
