Question

iment 6 From your ans confined gas is direct or inverse? Explain the first three questions and the shape of the curve in the plot of you think the relationship between the pressure and volume o f a 4. your answer sure to be if the volume of the syringe 5. Based on your data, what would you t the pres nswer was increased to 40.0 mL? Explain or s he volume of the syringe to be if t Based on your data, what would vou expect the pressure was decreased to 2.5 mlL? Explain or show work to support your 6. 7. What experimental factors are assumed to be constant in this experiment One way to determine if a relationship is inverse or direct is to find a proportional constant, k, from the data. If this relationship is direct, kP/V. If it is inverse, ke P.V. Based on your answer to Question 4, choose one of these formulas and calculate k for the seven pairs in your data table (divide or multiply the P and V values). Show the answers in 9. How constant were the values for k you obtained in Ouestion 8? Good data may show some minor variation, but the values for k should be relativelyconstant correcty expresses boy es aation representing Boyle's law. Write a verbal statement that EXTENSION 1. To confirm the type of relationship that exists between pressure and volume, a graph of pressure versus the reciprocal of volume (1/volume or volume-1) may also be plotted. To do this using LoggerPro, it is necessary to create a new column of data, reciprocal of volume, based on your original volume data. a. Remove the Curve Fit box from the graph by clicking on its upper-left comer. b. Choose New Calculated Column from the Data menu. c. Enter "1/Volume" as the Name, "1/V" as the Short Name, and "1/mL" as the Unit. Enter the correct formula for the column (1/volume) into the Equation edit box. To do this, type in "l" and “r, Then select "Volume" from the Variables list. In the Equation edit box, yo should now see displayed: 1/Volume". ClickDone d. Click on the horizontal-axis label, select "1/Nolume" to be displayed on the horizontal axis Chemistry with Compute

Explanation / Answer

Ans 4 :

The ideal gas law , pV = nRT relates the properties of gases such as pressure , volume , number of moles and temperature with each other.

According to the law , the graph can be plotted ,which indicates an inverse relationship between pressure and volume.

So when the pressure of the system is increased, the volume of gas decreases and conversely when the pressure of the system is decreased , the volume of the gas increases.
