The purpose of this lab was to learn about uncertainty and the propagation of error
in an experiment.
We also learned how to use the computer software to record and
analyze the data in several ways as well as how to generate a hardcopy of the data.
Theory
The slope of a line at a point in time is given by the following equation:
Slope = ∆T/∆t
Where T is the temperature with units of Celsius and t is the time with units of seconds.
Procedure
We began the experiment by turning on the laptop computer and loading up the
software that measures temperature.
We also plugged in the temperature gauge to the
computer and did a test reading to make sure it could measure the air temperature
correctly.
When we had a test reading done, we began a new reading to obtain our
temperatures for the analysis part of the experiment.
We started the first three seconds
