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.
