In an earlier video I demonstrated Boyle's law using some specialised equipment, consisting of a tube a air, trapped (and compressed) by a column of oil.
In this video I demonstrate a simpler version of the experiment: Compressing the gas using an air filled syringe connected to a digital pressure gauge.
Readings of pressure and volume can be taken from the video allowing an analysis to be carried out.
It should be noted that there is a significant systematic error in one of the readings, which I explain at the end of the video. I will pin a comment to the video giving a corrected figure, but some of you might wish to use the data to calculate the figure yourselves.
When carrying out the analysis I suggest plotting a graph of 1/P (y-axis) against Volume (x-axis). Make sure you leave some room to the left hand side of your y-axis(if using the raw data): You may well see the reason for this when you plot your graph.
