Ideal Gas Container: In the Ideal Gas simulator, you model gas dynamics using a closed container. This container can either feature a piston (default) or a rigid top wall. The container has sensitive hotspots into which you can plug in meters that measure pressure, density, volume, and temperature inside the container. The figure to the right indicates where you hook up those meters. To place the meters, you must click directly on a hotspot (note position of cursor).

At the hotspot on the lower right, you can hook up a gas tank (as indicated) to add gas to the container, or a vacuum pump to partially or completely evacuate the container.

To obtain an ultrascopic view, you only need to click inside the container with the Ultrascope View tool.

You can heat or cool the container using the heater/cooler element located under it.

In the Properties Box of the container, you can determine the kind of gas in the container: nitrogen, oxygen, helium, carbon dioxide or chlorine.

You can also choose to have a container with fixed walls or one with a movable top wall.

In the latter case, which is the default, the top wall is essentially a piston that you can pull up or push down to expand or compress the gas.

The piston is a separate, movable object. However, you can only operate (move) the piston in Run mode.
