verification of boyle's law

Question 1

how was the pressure of the gas varied during this experiment?

Answer 1

Boyle’s law apparatus uses a turning handle to compress an air column, increasing the pressure which can be read from a pressure guage

Question 2

describe how the pressure and the volume of the gas were measured

Answer 2

boyle’s law apparatus uses a turning handle to compress an air column, increasing the pressure which can be read from a pressure gauge. The volume of the gas in the column of air inside the apparatus can be read from markings placed on the outside of the glass column

Question 3

why should there be a delay between adjusting the pressure of the gas and recording its values?

Answer 3

to allow the apparatus to return to room temp, as boyle’s law requires constant temp.

Question 4

draw a suitable graph to show the relationship between the pressure and the volume of a fixed mass of gas

Answer 4

pressure against 1/volume

Question 5

draw a suitable graph to show the relationship between the pressure and the volume of a fixed mass of gas

Answer 5

pressure against 1/volume

Question 6

explain how your graph verifies boyle’s law

Answer 6

straight line graph through the origin confirms boyle’s law, that pressure is inversely proportional for a fixed mass of gas at constant temp
