Investigating at least one gas law

Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Boyle's Law: Pressure-Volume Relationship in Gases

Experiment #6 from Chemistry with Vernier

In this experiment, you will

  • Use a Gas Pressure Sensor and a gas syringe to measure the pressure of an air sample at several different volumes.
  • Determine the relationship between pressure and volume of the gas.
  • Describe the relationship between gas pressure and volume in a mathematical equation.
  • Use the results to predict the pressure at other volumes.

Pressure-Temperature Relationship in Gases

Experiment #7 from Chemistry with Vernier

In this experiment, you will

  • Study the relationship between the temperature of a gas sample and the pressure it exerts.
  • Determine from the data and graph, the mathematical relationship between the pressure and absolute temperature of a confined gas.
  • Find a value for absolute zero on the Celsius temperature scale.
