Aim:
Determine the relationship between the gas and the volume in the gas syringe, by using a “Gas pressure sensor”. (Which means, prove Boyle’s Law)

Aim of this is to prove the Boyle’s law. From out #1’s data table, we got very close value of constant, which is about the average of 1112.39 ± 4.6%. Thus, my prediction was right. If we increase the pressure, volume increases and if we increase the volume, pressure decrease. And we got about the same constant value each time so, I will conclude that we proved the “Boyle’s Law”, which is P1V1 = P2V2. For the graph, the slope of each graph become the constant k. The reason we have the almost the same slope (Not same because of the difference of linear fit and the curve fit) is a difference of the equation. For inversely proportional graph, the equation is y = a/x. On the other hand, for the direct proportional graph, the equation is y=ax.
For the inversely proportion, If we insert, P (Pressure) for y and V (Volume) for x, we will get PV = a, which is same thing as PV = constant, because “a” is a slope of the line. Then if we think about the direct proportional graph, If we insert, P (Pressure) for y and 1/V (Volume) for x, we will get same thing, PV = a, which is same thing as PV = constant like we got in the inversely proportional graph.
In conclusion, we determined the relationship between the volume of the gas and the pressure and proved the Boyle’s law.

*Boyle's Law:
Determine the relationship between Pressure and Volume of gases.
Aim: Determine the relationship between the gas and the volume in the gas syringe, by using a "Gas pressure sensor". (Which means, prove Boyle's Law)
Materials:
See attachment.
Procedure:
See attachment.
Hypothesis: The formula below is Boyle's Law.
And it equals to some constant "k". The volume of a fixed mass of gas at a constant temperature is inversely proportional to the pressure of the gas, thus we can rewri...
