week 7

1. What is the Newton’s Law of Cooling?
An object with a different temperature of its surroundings will finish having the same temperature of its surroundings.
The “rapidity” of loss of heat is proportional to the temperature difference, between the one of the object and the one of their environs.

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?
Temperature, the time that we found the body
Environ Temperature, the temperature and changes of it at any moment.

3. According to this Law, at what time approximately the death happened?
To know the time of death will be first to calculate the times and temperatures in
and the environment temperature also. Then the time you get k which is a variable you need to calculate the time. When you calculate the time with the temperature of the body at first you will, in this we take in consideration the healthiness of a person. When you get the time you will subtract it from the time you found the body.

4. How does the room temperature affect the time of death?
It is very difficult to calculate the time of a person’s death if it was found in snow
or it was raining. we can say that the environment is very importat because it is the independent variable and the bodies temperature is the dependent variable so everything would be according to the temperature and conditions of the environ.

5. How does an illness (e.g. fever) affect the time of death?
Because the temperature and loss of it will not be the same than those of a healthy
person. For example, if the person found had a fever, the temperature of the body was different.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?
It could be very exact, but you need to take into consideration the environment of it
and more.



This week was fun. Today in school the put me tape all over meL. They kind of wrap me in tape jajaja.
This project is very important for me because I will get to do what I am supposed to know and put it in practice.
All this week I went to church to some talks, I went with my family and one of my friends name Antonio”3
Tomorrow I will the project for this last semester for calculus. All my team is planning to do an amazing project.


Learning Goals: my goal would be to know how to visualize all the evidence that is in the case. How to recognize would be my main goal, because you need to be very sure about the data to get the most accurate time of death of a person.
