Translational distribution


Translational distribution

Clicking Select on the iconbar icon, or choosing Translation... from the iconbar icon menu will open the translational energy distribution dialogue. This dialogue has two tabs, one for the effect of differing mass at a fixed temperature, and one for the effect of differing temperature at a fixed mass. The type of comparison is selected by clicking on the appropriate tab at the top of the dialogue.


Effect of mass

The effect of mass dialogue is shown below.

The temperature (in K) at which the comparison is to be done must be entered in the top writable field.

It is possible to enter between one and five different masses to compare. If less than five masses are to be used, the first blank field will signal the end of the entered masses.


Effect of temperature

The effect of temperature dialogue is shown below.

The mass at which the comparison is to be done must be entered in the top writable field.

It is possible to enter between one and five different temperatures (in K) to compare. If less than five temperatures are to be used, the first blank field will signal the end of the entered temperatures.


At the bottom of the dialogue are three action buttons.

Close

Pressing Close will close the dialogue. If a graph is already showing this will also be closed. Any data in the writable fields will be retained for when/if the dialogue is reopened.

Clear

Pressing Clear will simply remove any data that has been entered in to the writable fields, leaving a blank dialogue. Note that only the data in the active tab will be cleared, and data in the hidden tab will remain.

Graph

Pressing Graph will open a new window showing the details entered in the dialogue as a graph of number of molecules plotted against their speed. An example graph is shown below.

Clicking Menu over this window will raise a menu with two options - Save as MultiPlot or Save as CSV. Following these options right will result in a standard Save as dialogue, allowing the data to be saved in the chosen format. The data may then be loaded in to the MultiPlot application, or into e.g. a spreadsheet for further use if needed. The menu (ready to save a MultiPlot file) is shown below.


These pages are best viewed in a CSS compliant browser. For RISC OS, Netsurf would be the browser of choice.
