Carbon is allowed to diffuse through a steel plate 12 mm thick. the concentrations of carbon at the two faces are 0.86 and 0.40 kg c/m3 in fe, which are maintained constant. if the preexponential and activation energy are 6.2 × 10-7 m2/s and 80,000 j/mol, respectively, compute the temperature (in k) at which the diffusion flux is 6.3 × 10-10 kg/m2-s.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
