Fick's Law of Diffusion
by Greg Crowther
Fick says how quick
A molecule will diffuse.
Delta P times A times k
Over D is the law to use.

(Fick) Pressure difference,
(Fick) Surface area,
(Fick) And the constant k
Are multiplied together.
(Fick) They're divided by
(Fick) Diffusion barrier
(Fick) To determine the exact rate of diffusion.
A short song about the Fick equation as written in the form that governs the diffusion of gases. It was written for BIOL 220 at the University of Washington. Ideally, "diffusion barrier" is pronounced so that it rhymes with "surface area." Also, the words "multiplied together" can be sung in harmony to reinforce the idea that factors are being multiplied.
