Effusion is the process where a gas flows through a small hole in a container.  Graham’s Law of Effusion says that the rate of effusion of a gas from a particular hole is inversely proportional to the square root of the MW of the gas (at constant temperature and pressure).  Describe why normal balloons filled with He tend to go flat faster than the same balloons filled with air.
