A crystal is composed of two elements, A and B. The basic crystal structure is a body- centered cubic with clements A at each of the corners and element B in the center. The effective radius of element A is 1.02 Å. Assume the elements arc hard spheres with the surface of each A-type atom in contact with the surface of its nearest A-type neighhor. Calculate (a) the maximum radius of the B-type atom that will fit into this structure, and (b) the volume density (#/cm') of both the A-type atoms and the B-type atoms.

Convective Mass Transfer between Phases

Mass transfer means the transport or movement of mass using streams, phases, components, and so on from one location to another.
