Explain whether smoke filling up a room is diffusion or not.

Smoke filling up a room is indeed an example of diffusion. Diffusion occurs when two or more sets of molecules intermingle and spread out. In this case, it would be the smoke molecules interacting and spreading out among the air molecules.

Yes it is diffusion ... explanation : diffusion is the movement of particles from high concentration to low concentration ... as the smoke rises at one corner of the room soon it spreads all over the room which is simply diffusionyes it is diffusion ... explanation : diffusion is the movement of particles from high concentration to low concentration ... as the smoke rises at one corner of the room soon it spreads all over the room which is simply diffusion
