please help me fill the constant K and questions 1 through 5

1. Is the relationship between the pressure and volume of a confined gas direet or inverse? 2. Calculate k (to 2 decimal places) for the seven data pairs in your data table. Calculate an average. Show your calculations in your lab notebook. Record the answers in the third column of the Summary Data Table. 3. Using P,V, and k, write an equation representing Boyle's law. 4. What would the pressure be if the volume of the syringe was increased to 40.0mL ? Include a calculation in your lab notebook to support your answer. 5. What would the pressure be if the volume of the syringe was decreased to 2.5mL ? Include a calculation in your lab notebook to support your
