Question

Q#1: Differentiate diffusion and effusion.

Answer 1

Heya mate.........

DIFFUSION is the process by which molecules move and travel from one place to another without requiring bulk motion. EFFUSION is the process by which molecules travel through a pinhole from a place of high concentration to low concentration. EFFUSION refers to the ability of gas to travel through a small pin-hole.

Hope this will help you....

${\bold{\underline{\underline{Defination \:of \: Diffusion \::}}}}$

Diffusion is the process by which molecules move and travel from one place to another without requiring bulk motion.

Diffusion happens when there are no holes or if holes in the barrier are larger than the mean free path.

${\bold{\underline{\underline{Defination \:of \: Effusion \::}}}}$

Effusion is the process by which molecules travel through a pinhole from a place of high concentration to low concentration.

Effusion refers to the ability of gas to travel through a small pin-hole.
