Answer
To complete Figure 10, you need to plot the points from Table 6 accurately, and draw a smooth line of best fit showing the inverse relationship between pressure and volume.
Step 4
Calculate the constant when the pressure of the gas was 300 kPa. Use Table 6.

Answer
Using the equation:
extpressureimesextvolume=extconstant
When pressure = 300 kPa and volume = 10 cm³:
300imes10=3000extkPacm3
Therefore, the constant = 3000 kPa cm³.
Step 5
How does increasing the volume affect each of the following quantities?
