Boyle’s Law and the Mass of a Textbook
Description: After using a syringe to confine a fixed volume of gas at room temperature, the pressure on the gas is increased by balancing books or weights on the syringe plunger. The resulting gas volumes are recorded and the data are examined to illustrate Boyle’s Law.
