![Some farts stink. This is mostly due to the presence of small quantities of hydrogen sulfide gas and mercaptans. The diffusion coefficient of H2S gas in air is 0.2x10
-m²/s.
Imagine that you fart 1 meter away from a classmate. How long might you expect it would take for your classmate to smell this unwelcome olfactory intrusion if
diffusion were to be the main means of gas dispersal?

Does your experience with intestinal gas jibe with this value? What are a couple of good reasons why not?
