An important element in the gases simulation is the ability to save the P, V, T, and n data from each of the experiments to the lab book and later copy that data to an external spreadsheet program for further analysis. This is done by clicking the Save button (located on each experiment) or the Save Data button in the Live Data tab. These buttons will create a table in the electronic lab book where all the P, V, T, and n data will be saved as the various parameters are changed in the experiment. The saving process will continue automatically for each change in an independent variable until the Save/Save Data button (now labeled Stop) is clicked again. Clicking on the lab book will bring up the lab book tab displaying all the saved data in columns. This data can be selected, copied, and then pasted into an external spreadsheet program for further analysis.
