Stefan's law describes the mass transfer by________________?
Correct answer: C. Both A. & B.
- A. Diffusion
- B. Bulk flow
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
Stefan's law treats diffusion through a stagnant component while also accounting for the bulk motion caused by unequal molar fluxes. It therefore includes both the diffusive and bulk-flow contributions to mass transfer.
