Gases are made up of tiny particles. The particles are in constant motion and exert pressure when they strike the walls of their container. In this simple experiment, you will use a computerinterfaced pressure sensor and an air sample in a stoppered flask to study the relationship between gas pressure and temperature. The volume 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.
In this experiment, you will
Use a pressure sensor to measure the pressure of an air sample at several different temperatures.
Make a table of the results.
Graph the results.
Predict the pressure at other temperatures.
Describe the relationship between gas pressure and temperature with words and with a mathematical equation.
