Charles's law: The V-T relationship under constant pressure
255255204
(If this button doesn't turn gray when clicked, click it again.)
Instruction: In this activity, we will investigate the relationship between volume and temperature for a gas under constant pressure. A constant external force is exerted on the piston to maintain constant pressure of the gas.
Click the "Automatically heat the gas" button to start heating the gas gradually. A hourglass image will appear at the lower-right corner of the window, which indicates that a process is going on to heat up the gas. While the model is running, observe the graph on the right. When the hourglass image disappear, meaning that the heating process ends, the simulation will automatically stop. Right-click (Windows) or CTRL+click (Mac OS X) on the graph and select the "Take a Snapshot" item from the popup menu to record the graph. The snapshots you take will be automatically included in the final report that you will generate at the end of this series of experiments.
