CHEM 1111: General Chemistry I Lab BOYLE’S LAW Name Partner Date Section Results: Enter the volume and pressure data in the following table. One way to determine if a relationship is inverse or direct is to find a proportionality constant, k, from the data. If this relationship is direct, k = P/V. If it is inverse, k = P•V. Calculate k for the seven ordered pairs in your data table (divide or multiply the P and V values). Volume Pressure Constant, k, when P and Constant, k, when P and V V are inverse, (P / V) are direct, (P • V) 1 CHEM 1111: General Chemistry I Lab Post-lab Questions: Question Answer If the volume is doubled from 5.0 mL to 10.0 mL, what does your data show happens to the pressure? Show the pressure values in your answer. If the volume is halved from 20.0 mL to 10.0 mL, what does your data show happens to the pressure? Show the pressure values in your answer. If the volume is tripled from 5.0 mL to 15.0 mL, what does your data show happened to the pressure? Show the pressure values in your answer. From your answers to the first three questions and the shape of the curve in the plot of pressure versus volume, do you think the relationship between the pressure and volume of a confined gas is direct or inverse? Explain your answer. Based on your data, what would you expect the pressure to be if the volume of the syringe was increased to 40.0 mL. Explain or show work to support your answer. Based on your data, what would you expect the pressure to be if the volume of the syringe was decreased to 2.5 mL. How constant were the values for k you obtained in Data table? Good data may show some minor variation, but the values for k should be relatively constant. 2 CHEM 1111: General Chemistry I Lab Graphs: Paste the two graphs below 3
