Experiment 1: Charles’ Law
I
...
Discussion
According to the results, the volume of the gas increased as temperature
increased
...
Using the equation
from the graph of the data, the temperature was determined to be -269

Instead of using the rubber tubing, a syringe can be inserted into the rubber
stopper
...
The buret can be used as a manometer so that
the pressure can be approximated by measuring the height of the liquid and using its
density to correct the pressure
...

...
We want to get the volume of
the gas using pressure, which is contributed by the water in the flask, that’s why the
presence of even little water in the flask will harm the results
...
The gas you studied is actually air which is a mixture of gases, should this cause any
error in the experiment?
Yes, this volume of air is saturated with water vapor that contributes to the
total pressure in the flask, the volume must then be corrected to that of dry air at
atmospheric pressure
...
Conclusion
Volume of a gas is directly proportional to temperature, so as the temperature
rises, the volume increases as the pressure and the amount of gas remained constant
throughout the experiment
...
The experiment was a success as it complied with Charles’ Law
