Use the following web page to read about units of pressure. Teach yourself how to calculate pressure from force and area (pressure is defined as the force per unit area (P = F/A). This calculation results in units of pressure called newtons per square meter, N/m^2). Teach yourself how to convert to bars, millibars, atm, and torr.
Here is the site:

Navigate as follows: Mechanics>>>Fluids>>>Pressure. Read related linked documents and play with the calculation tools provided on the pages you find.

Here is the page we looked at in class which included some applets regarding gas laws:

Specifically, here is the Properties of Gases Applet

Here is a page about evaporative cooling, as we discussed in class: http://www.colorado.edu/physics/2000/bec/evap_cool.html
