Date Created: December 2 nd , 2009 Name: Tyler Campos Date Submitted: December 4, 2009 Partner: Conor McKenna Instructor: Bing Yan Properties of Gases Objectives: To study the dependence of the volume of a gas on temperature and pressure. Part A: Boyle’s Law Temperature °C h= length of airspace (mm) 25 50 35 45 50 50 65 55 75 55 95 60 Part B: Boyle’s Law Syringe Vol (mL) Sensor Pressure (mmHg) Syringe Vol (mL) Sensor Pressure (mmHg) 4 1 11 -391 1 657 12 -417 2 352 13 -437 3 144 14 -453 5 -102 15 -470 6 -177 16 -484 7 -243 17 -497 8 -294 18 -507 9 -335 19 -517 10 -366 20 -526 Sample Calculations: Charles’ Law V=a 2h Boyle’s Law To calculate the air pressure of each volume in the syringe: Pair=Psensor+Patm To calculate PV, we multiplied the pressure x the volume. PV=?
