Chemistry: Boyle's Law

Objectives

• 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 gas pressure and volume.
• Use the results to predict the pressure at other volumes.
• Mathematically describe the relationship between gas pressure and volume.
• Evaluate an inverse mathematical relationship.
• Generate and analyze a power regression model.
• Linearize an inverse relation.

About the Lesson

This activity makes use of the Gas Pressure Sensor in an inquiry activity that enables the student to understand Boyle’s Law through experimentation and data collection.
As a result, students will:

• Built a mathematical model to show the inverse relationship between gas pressure and gas volume.
• Analyze that mathematical model, and make predictions from the model through interpolation and extrapolation.
• Apply Boyle’s Law to the real-life situation of human respiration.
