Place the micro pipet into a double-post clamp, with the bulb centered in the clamp.
Record the volume (height) of the air space above the colored liquid, by using a metric ruler,(mm).
Turn the clamp to the right. This will increase the pressure on the bulb.
Record the volume (height) of the air space, in mm.
Turn the clamp to the left. This will decrease the pressure.
Record the volume (height) of the air space, in mm.

Analysis:
1. Describe the change in volume of the air space when the pressure was increased on the bulb.
2. Describe the change in volume of the air space when the pressure was decreased on the bulb.
3. What type of relationship exists between pressure and volume?
4. What type of relationship exists between pressure and volume?
Conclusion:
Answer the following questions.
According to Boyle’s law, the product of the pressure (P) and volume (V) of a fixed mass of gas at constant
temperature is a constant (K). The following table contains pairs of pressure and volume readings for a gas
under such conditions.
For each pair of readings, calculate the value of K.
11. Now plot on the following grid the values of P and V from the table above. Connect the points with a
smooth curve.
