6.5. Relate MW and speeds of molecules using Grahams
law.
Effusion is the movement of gas molecules from an enclosed container through
a small hole into a vacuum.
The following animation will show an illustrion of the effusion
of a gas, at the molecular level .
Explore how the molecular weight of a gas influences the rate of effusion.
Choose hydrogen gas first. Count the number of molecules of hydrogen that escape
in 30 sec.
Predict the rate of effusion for for oxygen gas. Then do the simulation and
compare your calculated value to the experimental value.
