Introduction
In this simple experiment, you will use a Gas Pressure Sensor and a gas syringe to study the relationship between gas pressure and volume. Temperature and amount of gas will be kept constant. The results will be expressed in words, in a table, with a graph, and with a mathematical equation. These are four methods commonly used by scientists to communicate information.
This experiment is similar to one first done by Robert Boyle in 1662—without the use of a computer, of course. The relationship you will discover is known as Boyle’s law.
