depression was to be measured from may have been different even though the members of the group all decided that.
measurements should be taken from the end of the rubber stopper. The human error made here would have been a.
large factor in determining the volume of the syringe, which as a result may not be accurate. .
The second problem that played a large part in determining the results would have been due to the high amounts of.
friction that was existent between the wall of the syringe and the rubber stopper. Because of this, each time a mass.
was added, the plunger had to be forced down past it's desired depression and then assisted back up until it reached.
its minimal depression. In this case, because the minimal depression recorded depended much on the members of the.
group, this meant that the results may have slight inaccuracies involved with them. .
The assumptions made may also not be true. In reality, the temperature in the classroom could have been fluctuating.
at the time, even though it may have been in minute amounts. This would have played a role in the pressures determined.
because temperature is known to be proportional to pressure and therefore would have affected the atmospheric.
pressure calculations. Also, the assumption that the equipment used were free from faults would have played a.
cosiderable amount in the results obtained especially if it were to be untrue.
With the results obtained, when PV was calculated, a constant value was not obtained. Instead the values varied from.
the 0.1 mark to the 2.3 mark. This result is most likely due to the errors involved in the prac as described earlier. The.
product of PV increasing would have meant the temperature increased in the room as the prac was conducted. When.
pressure was plotted against the 1/volume, the points were arrranged closely to a straight line. This verified the.
relationship that when pressure rises, volume decreases, and vice versa.
