Boyle's Law

Boyle’s law states: ‘If the temperature remains constant, the volume of a given mass of gas is inversely proportional to
the absolute pessure.
Through the conduction of this prac, this was found to be true. The pressure inside the syringe had to increase as the
volume decreased because the molecules inside had less space to collide with one another and the wall. Therefore as
the molecules had less volume to move around in, they would be colliding more often with eachother and the wall,
increasing the pressure inside the syringe. It is therefore correct to say that :

Some assumptions were made when conducting this prac. They include;
(1)that temperature remained constant throughout the course of the prac and so the atmospheric pressure remained
constant,
(2)that all the equipment used were free of faults and completely efficient.

The assumptions made in the prac played a major role because if the assumptions were not true at the time, this would
mean that the results collected are not entirely accurate. Especially when considering that there was human error also
involved, this would have played a part in the data collected.

There were a few problems that were found when conducting the prac. The first problem encountered was that due to
the syringe used not having mL calibrations, the measurements had to be found using a ruler which at times had to be
held out atleast 5 to 10 cm out infront of the syringe. This was because of the platform block and books depressed too
much to be able to fit the ruler up against the syringe. Therefore, the person holding the ruler also had to read the
depression when the ruler was held out a fair distance away. The error that could have resulted from this would be
that the reader because the ruler was held up in the air, the reader’s arm could have moved slightly down or up while
the measurements were read. Also because different people made the measurment...
