Why we have made this experiment:
We have made this experiment in order to see the relation between pressure and temperature.
What have we made:
In order to gatther the data we have connected the digital thermometer and pressure indicator to the computer. We put the water to boil and we connect the bouth sensors. We open the logger and data will be gathered automatically.
Data gathered: (The data between this numbers shown has been taken in acount for the graph, but it´s extention would be to big for the table).

What we have seen on our computers:
Graphs:
To sum up all the graphs:
Conclusion:
We can conclude, seeing the graph, that the pressure doesn´t change with temperature. However, a lot of informatic problems can ocurr, incluiding a problem with the pressure sensor.
