if it is recycled, it comes back as a paper product sooner or later. If it goes to a land fill site, it is just wasted
it comes and goes...
(a) Compare interstitial and vacancy atomic mechanisms for diffusion. (b) Cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion. Solution (a) With vacancy diffusion, atomic motion is from one lattice site to an adjacent vacancy. Self-diffusion and the diffusion of substitutional impurities proceed via this mechanism. On the other hand, atomic motion is from interstitial site to adjacent interstitial site for the interstitial diffusion mechanism. (b) Interstitial diffusion is normally more rapid than vacancy diffusion because: (1) interstitial atoms, being smaller, are more mobile; and (2) the probability of an empty adjacent interstitial site is greater than for a vacancy adjacent to a host (or substitutional impurity) atom.
true.
ok, you know if you are on a asocial networking site and chatting to get to the person's comp it goes up to the satelite and comes back down to their comp this also happens with t.v. ....
the simplest of the point defects is a vacancy or vacant lattice site ,one normally occupied from which atom is missing is called vacancy a self-interstitial is an atom from a crystal that is crowded into an interstitial site , a small void space that under ordinary circumstances is not occupied.
Alveoli are site of gas exchange. Actual diffusion of gases occurs at interstitial space between capillaries and alveolar cells.

the organ that is involved in gas exchange is the lung. the specific lung structure that is the site for gas exchange is the alveolus which is part of the alveoli, which is found in the lung.
What "happens" depends on you.
