Question

Define diffusion in gas with example?

Answer 1

diffusion of gases is basically when a gas spreads itself around its container. best example.....farts. when you fart you don't smell it immediately, it takes a while, thats because when it leaves your tush all the molecules are bunched together. then once it enters the surrounding environment the fart molecules start bumping off air molecules (kind of like pool balls hitting off each other) and spreading themselves around the room. that's when the stink hits you. 
hope that helps!

Answer 2

Answer:

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.
