- Using and Installing the Program Gas Law
-
- Installing GasLaw on your hard drive:
- To install GasLaw on your hard drive type start windows and click on File in the upper left hand corner
- of Program Manager. If using Windows 95 click on Start in the lower left hand corner. Choose Run from
- the file menu and type and enter path\install where path is the location of the gaslaw files. For example, if
- the files are on the root directory of A drive you would enter A:\install. Install will create a directory called
- C:\GASLAW, copy all of the appropriate files, and create the necessary icons.
-
- Purpose of the program
- It is difficult for students to visualize the behavor of gases on the molecular level. this program
- allows the student to see an graphical representation of molecular motion of gases and how changing
- pressure, temperature, volume, and moles can affect that motion. The Automaticautomatic section of the
- program will take them through a step by step process where parameters are changed and the effect on the
- system can be visualized as the changes occur. A laboratory that can be used with the automatic portion of
- the program is included with the registered version. (See register.txt). The ideal gas law can be examined
- as well as the Maxwell-Boltzmann distribution of molecular kinetic energy as temperature is changed. The
- manualmanual portion of the program allows the student to vary pressure, moles, volume, and temperature
- as they desire to see the effects on the system. The manual portion of the program is disabled in the
- unregistered version.
-
- Using the Program:
-
- Gas Law Menu
- This menu can be used to exitexit the program.
-
- Start Item
- Clicking on this item will allow the user to start the molecules in motion. This item is only available
- when the program is in the manual mode. To stop the motion of the molecules click on Pause.pause
-
- Pause Item
- Clicking on this item will allow the user to stop the molecular motion. This item is only available
- when the program is in the manual mode. To start the motion of the molecules click on Startstart
-
-
- Change Variables/Constants Item
- When choosing this menu item a dialog box will be presented with a number of checkboxes.
- Check the boxes of the parameters you want to vary. You may choose only two items a one time. This item
- will only work when the program is in the manual mode. Only parameters that are variables can be
- changed by clicking on the parameter scroll barsparameter.
-
- Mode Menu
- When choosing this menu you may change the mode of the program from manual to automatic and
- back. In the unregistered version of the program the Manual mode will not function. See register.txt for
- more information. Click on Manualmanual or Automaticautomatic.
-
- Next Item
- When choosing this the next portion of the automatic sequence of the program will be presented.
- This option only works when the program is in the automatic mode.
-
- Varying parameters.
- In order to change volume, pressure, temperature or pressure it must have variable written by the
- appropriate scroll bar. To change a parameter from a constant to a variable or a variable to a constant click
- on ChangeVariables/Constantschange on the Menu Bar. Use the mouse to change a parameter either by
- clicking on the arrow keys of the scroll bar or by dragging the thumb control of the scroll bar. The thumb
- control is the movable square on the scroll bar and it can be dragged by clicking the left mouse button on
- the control, moving the mouse to the desired location and then releasing the left mouse button. If changing
- a variable results in the other variable going out of range any further change will be prevented.
-
- Manual Mode
- This mode allows the user to vary pressure, temperature, moles, and volume as desired. To
- change any parameters use the scroll barsparameter in the upper left hand corner of the screen. This
- mode will not function in the unregistered version of the program. See register.txt for more information.
-
- Automatic Mode
- This mode will walk the user through changes in moles, pressure, temperature, and volume.
- Everything is changed automatically so all the user need do is click and watch. After a sequence is
- completed and the user is ready for the next step click on Nextnext on the main menu.
- A laboratory which can be used with this portion of the program is included with the registered copy. See
- register.txt for more information.
-
- Exit
- To quit the program select this menu item or press Alt-x.
-
- Help can be obtained at any time by clicking on the Help Menu item.
