Question

describe effusion and diffusion

and difference between diffusion and effusion ​

Answer 1

Answer:

Effusion

The diffusion of a gas at high pressure into low pressure or vaccum, through a small hole is known as Effusion.

Diffusion

The ability of gases to mix spontaneously and to form a homogenous mixture is known as diffusion.

Difference between effusion and diffusion :

In diffusion case, the gas spontaneously streams through a porus partition. While in effusion case, the gas is forced out through a small hole by applying some external pressure. However both the processes are essentially the same.
