The code is WEST-VIRGINIA-SUMMER-2020 An ideal gas is a hypothetical gas whose pressure, volume, and temperature follow the relationship PV = nRT. Ideal gases do not actually exist, although all real gases can behave like an ideal gas at certain temperatures and pressures. All gases can be described to some extent using the Ideal Gas Law, and it is important in our understanding of how all gases behave. In this assignment, you will derive the Ideal Gas Law from experimental observations. The state of any gas can be described using the four variables: pressure (P), volume (V), temperature (T), and the number of moles of gas (n). Each experiment in Virtual ChemLab: Gases allows three of these variables (the independent variables) to be manipulated or changed and shows the effect on the remaining variable (the dependent variable). 1. Start Virtual ChemLab, select Gas Properties, and then select Ideal Gas Law from the list of assignments. The lab will open in the Gases laboratory. 2. Use the balloon experiment already setup in the laboratory to describe the relationship between temperature (T) and volume (V). You can increase and decrease the temperature using the lever on the Temperature LCD controller to determine the effect on volume. 3. You can also change the temperature by directly entering numbers into the LCD controller. 4. Press ‘save’ to initiate the saving of data. 5. Enter at least five different temperature values and record the pressure (this is done automatically in the lab book) 6. Press ‘stop’. If you now open the lab book you will see a link to ‘gases’. If you click on this link you will see that data you have recorded. 7. Copy and paste this data into excel. Plot a scatter graph of volume (y-axis) vs. temperature (xaxis). Note that the dependent data(volume) is on the left when you first copy it into excel. If you follow the instructions in the ‘intro_excel’ document (provided on ecampus) it will plot the graph with the volume on the x-axis (incorrect). A quick fix for this is to click on the volume column header (so it is highlighted). Right-click and then hit copy. Then go to the empty column on the right immediately following your data. Click on the empty column header (it will highlight the column), then right-click and click paste. Now select temperature and the volume column (on the right) and then add a scatter graph. 8. Add a trend line to your graph (see ‘intro_excel’ document’). Label the graph and the different axis including units. Format the axis if they need to be (see ‘intro_excel’ document’). 9. Repeat the above steps but now varying moles and looking at its impact on volume. Plot a graph of volume vs number of moles and label the graph and axis as in (8) 10…Repeat the above steps now varying pressure and look at its impact on volume. This time plot a graph of 1/volume (y-axis) against pressure. You will need to create a new column with the 1/volume values in. 11. Based upon your graph, write the appropriate mathematical relationship between volume and temperature Write the mathematical relationship using the proportionality symbol (). 12. Based upon your graph, write the appropriate mathematical relationship between volume and moles Write the mathematical relationship using the proportionality symbol (). 13. Based upon your graph, write the appropriate mathematical relationship between volume and pressure Write the mathematical relationship using the proportionality symbol (). 14 Write one combined proportion to show the relationship of volume to pressure, temperature and moles. 15. This proportional relationship can be converted into a mathematical equation by inserting a proportionality constant (R) into the numerator on the right side. Write this mathematical equation and rearrange with P on the left side with V. 16. This equation is known as the Ideal Gas Law. Using data for volume, temperature, pressure and moles from one of the gas experiments, calculate the value for R with units of LatmK-1mol-1. (Show all work and round to three significant digits.)
