Unit 2- Assignment B
Keeping up the standards:
Aim:
The main aim of this experiment was to obtain data using different equipment to
construct cooling curves and use cooling curves to determine the cooling rate of
different substances.
Calibration of the digital thermometer:
The digital thermometer was calibrated by placing it into ice water, and
recording the temperature. This was then repeated twice so three readings could
be obtained in order to work out an average. The digital thermometer was then
placed into boiling water, which was repeated three times, so we could get an
average for it.

Calibration of the spirit thermometer:
To calibrate the spirit thermometer, it was firstly placed into ice water and the
temperature was recorded. This was repeated again twice so we had three
readings, and could work out an average. The spirit thermometer was then
placed into boiling water and like the ice water, three readings were taken so we
could take an average. The results were compared with the digital thermometer,
so we could decide which one would have been best to use.

The table shows that the spirit thermometer when put in ice water, is on average
0.1° above the digital thermometer. In boiling water, the table also shows that
the spirit thermometer measures 4.1° above the digital thermometer.
Overall the table tells us that on average, the spirit thermometer measures 2.1°
above the digital thermometer, meaning that throughout all of the readings
taken using the spirit thermometer should have 2 degrees subtracted from them
throughout the experiment.
