Boyle’s Law: Pressure and Volume Essay Example

recording data, and a blue data link will appear in the lab book. To help keep track of your data links, enter ‘Ideal Gas 1’ next to the link.

4. Zoom Out by clicking the green arrow next to the Save button. Click Return Tank on the gas cylinder. On the table underneath the experimental chamber is a switch to choose Real gases or Ideal gases. Click on the Ideal Gases and choose the cylinder labeled Ideal 8 (Ideal 8 MW = 222 g/mol). Click on the balloon chamber to Zoom In and set the temperature, pressure, and moles to 298 K, 1.00 atm, and 0.300 moles, respectively. Repeat the experiment with this gas labeling the data link as ‘Ideal Gas 8.’

5. Zoom Out by clicking on the green arrow next to the Save button. Click on the Stockroom and then on the Clipboard and select Balloon Experiment N2. Again, set the temperature, pressure, and moles to 298 K, 1.00 atm, and 0.300 moles, respectively. You may have to click on the Units button to change some of the variables to the correct units. Repeat the experiment with this gas labeling the data link ‘Real Gas N2.’

6. Select the lab book and click on the data link for Ideal Gas 1. In the Data Viewer window, select all the data by clicking on the Select All button and copy the data using CTRL-C for Windows or CMD-C for Macintosh. Paste the data into a spreadsheet program and create a graph with volume on the x-axis and pressure on the y-axis. Also create a graph for your data from Ideal Gas

8 and Real Gas N2.

7. Based on your data, what relationship exists between the pressure and the volume of a gas (assuming a constant temperature)? The pressure varies with the volume, as the pressure increases the volume decreases.
