Question

Of all gases hydrogen diffuses fastest at any temperature you tell from this?

Answer 1

Answer:

At any given temperature, small, light molecules (such as H 2, hydrogen gas) diffuse faster than larger, more massive molecules (such as N 2, nitrogen gas) because they are traveling faster, on the average (see heat ; kinetic-molecular theory of gases ).

Answer 2

Because hydrogen has smallest size particles and it's molecular mass is very low so it diffuses faster than any other gases.
