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).
