Boyle’s Law

Purpose:

Using experimentally collected data, plot the pressure versus volume curve that shows the inverse, hyperbolic relationship of Boyle’s Law.

Contents:

One (1) Wooden Base

One (1) Wooden Top

Two (2) Small plastic caps (one is spare)

One (1) Syringe with piston

5-10 books (must be the same)

Procedure:

  1. Assemble theBoyle’s Law apparatus.
  2. Record the volume of the syringe with zero books on top.
  3. Place one book on the apparatus. Measureand record thevolume of air in the syringe.
  4. Measure and record the volume of air until _____ books have been placed on the apparatus.
  5. Make a graph of volume vs. pressure for each trial.

Assembly of Boyle’s Law Apparatus

  1. Place the large wooden base on a firm surface with the larger hole down.
  2. There should be no small plastic cap on the end of the syringe at this point. Pull the plunger out of the syringe.
  3. Press the syringe body into the hole on the topside of the base.
  4. Press the top end of the syringe plunger into the hole in the wooden top. (The thin wooden block.)
  5. Reassemble syringe.
  6. Draw a measured volume of air into the syringe and press the small plastic cap over the nozzle end of the syringe under the large block.

Questions

1. If 150 mL of a gas at 450 torr has its pressure increased to 200 kPa, what will the new volume be?

2. If a gas at a pressure of 2.30 atmospheres changes to standard pressure, what was the original volume of the gas if the new volume is 52.3L?
