Ceneval week
This week, we had the famous Ceneval test, and there was a lot of pressure on us, because we had to get good grades in it, so I was kind of nervous to do it, but we finally did it, and it wasn't that hard, so I hope I get a good score.

Newton's Law of cooling...
1. What is the Newton’s Law of Cooling?
The difference between an object'’s temperature and the temperature of the
surrounding environment.
2. What variables in your problem correspond with the variables in the Newton’s
Law of Cooling?
The temperature of the body and the temperature of the environment
3. According to this Law, at what time approximately the death happened?
9:36 a.m.
4. How does the room temperature affect the time of death?
If it is warmer or cooler the body decreases faster or slower the temperature
5. How does an illness (e.g. fever) affect the time of death?
The temperature of the body wouldn’t be the standard.
6. How exact is the approximation of the Newton’s Law of Cooling for predicting
the time of death?
It is kind of exact, but there are other factors to consider to get an exact time.

Questions...
4. What methods are commonly used to find the time of death?
*The rate method. Measuring the change produced by a process which takes place at aknown rate which was either initiated or stopped by the event under investigation, i.e.death.
*The concurrence method. Comparing the occurrence of events which took place atknown times with the time of occurrence of the event under investigation, i.e. death.
5. What factors are considered in Algor Mortis?
Climate, the "size" of the body, clothing and coverings, movement and humidity of the air, Immersion in water.
6. How does the environment affect the time of death?
After the body cools, it begins to reach the environmental temperature.
7. What can you tell about the different methods of temperature reading of the body?
Do they make a difference in the results?Well, maybe they do, because they are taken in very different ways, so there can be a possible change.
