Evaporation Container: In the Evaporation simulator, you model the evaporation of liquids using a closed or open container. This vessel contains liquid in its lower half and gas in its upper half. The container has sensitive hotspots into which you can plug in meters that measure pressure and density of either air or liquid vapor, and the temperature of air, liquid vapor, or the liquid. 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). The hotspot to the lower right is for temperature meters only. |
To obtain an ultrascopic view, you must click near the interface between liquid and air with the Ultrascope View tool (see figure above). 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 liquid in the container: water or methanol. You can also choose the initial temperature (cool day, room temperature, or warm day) and the initial humidity (20%, 40%, or 60%). The container can either be closed (default) or open. If you have an open container, the density, temperature and pressure of both air and liquid vapor stay constant.
