This app explores K_H and the migration of gas molecules between air and water.

Select a gas from the Scenario menu at top left to begin. This loads values for that gas into the worksheet at left.

Press the Run button to calculate the equilibrium value for C_W, the amount of gas in the water. The final value for C_W is independent of its initial value. Results are animated on the pond display.

Try running each Scenario first. Then edit values on the Worksheet to explore from there. K_H varies depending on temperature.
