Draw profiles of T, qx, and qx'' vs x for a planar wall made of a material with a constant thermal conductivity, k, with a uniform (positive) energy generation rate. Consider a situation where the temperature on each side of the wall is held fixed at the same value.

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
