5. Based on your data, what would you expect the pressure to be if the volume of the syringe was 6. Based on your data, what would you expect the pressure to be if the volume of the syringe was 7. What experimental factors are assumed to be constant in this experiment? increased to 40.0 mL. Explain or show work to support your answer decreased to 2.5 mL 8. One way to determine if a relationship is invese or direct is to find a proportionality constant, k from the data. If this relationship is direct, k PIV. If it is inverse, k P.V. Based on your answer to Question 4, choose one of these formulas and calculate k for the seven ordered pairs in your data table (divide or multiply the P and V values). Show the answers in the third column of the Data and Calculations table

Explanation / Answer

5. According to Boyle's law, the volume of a gas is inversely proportional to its pressure.

i.e. P1V1 = P2V2

The initial volume was not mentioned. For suppose the initial volume of syringe = 10 mL and initial pressure (P1) = 1 atm, the final volume (V2) = 40 mL

Now, 1 atm * 10 mL = P2 * 40 mL

i.e. P2 = 0.25 atm

6. According to Boyle's law, P1V1 = P2V2

For suppose the initial volume of syringe = 10 mL and initial pressure (P1) = 1 atm, the final volume (V2) = 2.5 mL

Now, 1 atm * 10 mL = P2 * 2.5 mL

i.e. P2 = 4 atm

7. According to Boyle's law, at constant temperature and the constant number of moles, the volume of the gas is inversely proportional to its pressure.
