Verification of Boyle’s Law using a pressure sensor and a datalogger T.H. The Professional Development Service for Teachers is funded by the Department of Education and Skills under the National Development Plan

Apparatus PDST Resources for Leaving Certificate Physics 2

Apparatus PDST Resources for Leaving Certificate Physics 3

Method Connect the pressure sensor to the datalogger PDST Resources for Leaving Certificate Physics 4

Method Set the syringe to 20 cm3. PDST Resources for Leaving Certificate Physics 5

Method Connect the syringe to the pressure sensor. PDST Resources for Leaving Certificate Physics 6

Method Open your datalogging software, e.g. DataStudio. PDST Resources for Leaving Certificate Physics 7

Method Click “Create Experiment”. PDST Resources for Leaving Certificate Physics 8

Method Choose the correct sensor. PDST Resources for Leaving Certificate Physics 9

Method Choose “Digits” from the display list. PDST Resources for Leaving Certificate Physics 10

Method Click “Start” and record the volume of air in the syringe and the pressure, p, from the display. PDST Resources for Leaving Certificate Physics 11

Graph the pressure, p, against 1/V. Repeat, changing the volume, V, of air in the syringe by pressing the piston. Wait a moment for the air to return to room temperature after changing its volume. Graph the pressure, p, against 1/V. PDST Resources for Leaving Certificate Physics 12

Use the following table to draw a suitable graph to verify Boyle’s law. PDST Resources for Leaving Certificate Physics 13

Remember! Boyle’s law states that, for a fixed mass of gas, the pressure is inversely proportional to the volume as long as the temperature remains constant. PDST Resources for Leaving Certificate Physics 14

Note: Don’t forget to draw a new table, using 1/V instead of V. PDST Resources for Leaving Certificate Physics 15

Graph the points from the second table and draw the best straight line. PDST Resources for Leaving Certificate Physics 16

This verifies Boyle’s law. A straight line graph through the origin shows that p is proportional to 1/V. This verifies Boyle’s law. PDST Resources for Leaving Certificate Physics 17
