Newton's law of cooling
Select the variables so that you measure the time from 10:00 a.m. and the surrounding temperature, which is 22°C. Newton’s law of cooling: tells that the body temperature will change proportionally to the difference between the body temperature and the surrounding temperature. Try setting up equations and fitting a model to the data. An example of how this is done is shown below.
Try it out:
This will yield the following system of equations:
You can add the lines
8.3 = C a0 4.6 = C a1You can solve the system of linear equations in different ways. Here is a suggestion:
|1.||In the input line create two points |
|2.||Write the model function in the input line |
|3.||Adjust the model with the sliders to go close to or through the points |
y = 22and
y = 36.8to indicate the temperature of the surroundings and the body temperature.
