In this virtual laboratory you will use an on-line simulation from the University of Colorado PhET group to explore how the bulk properties of a gas are related to the behavior of the individual gas molecules.
Link to the simulation: http://phet.colorado.edu/simulations/sims.php?sim=Gas_Properties Click "Run Now!".
Explore the interface! (Click "Help" for hints.)
You can pump two types of molecules into the chamber.
You can specify constant volume, pressure, or temperature.
You can work in an environment with or without gravity.
You can heat up the gas in the chamber.
You can use various measuring tools. (Explore what they can be used for.)
In a gravity-free environment verify the predictions of the ideal gas law.
(A) Put some gas in the chamber. Keep the volume constant and explore the relationship between pressure and temperature.
(B) Put some gas in the chamber. Keep the temperature constant and explore the relationship between pressure and volume.
(C) Put some gas in the chamber. Keep the pressure constant and explore the relationship between volume and temperature.
(D) Put two species of gas into the chamber. Keep the temperature constant and compare the average speeds of the two types of particles.
In an environment with gravity explore how the pressure varies with height.
