Draw schematically the diffusion coefficient d in a log scale versus 1/t (t is temperature in kelvin) for diffusion (i) within crystal bulk, (ii) along grain boundaries, and (iii) on crystal surfaces. briefly explain the reasons why the slopes are different.

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.
