An atom moves into the vacancy’s original position, creating a new interstitial position

An atom moves into an interstitial position, creating a new vacancy in the atom’s original position

Larger chemical species move between the spaces around smaller atoms

Atoms move into the vacancies of other atoms

Smaller chemical species move between the spaces around larger atoms (correct)

The relationship between temperature and diffusion coefficient

The mechanism of interstitial diffusion

The change in concentration gradient over time

How much of something moved and how fast did it move (correct)
