Drugs, Dyes, & Mass Transfer: Crash Course Engineering #16

Today we’re talking about mass transfer. It doesn’t just apply to objects and fluids as a whole, but also to the individual molecules and components that make them up. We’ll see that transfers of mass need their own driving force, discuss diffusion, and use Fick’s Law to help us model mass transfer.

Crash Course Engineering is produced in association with PBS Digital Studios.
