Most of the earth's volcanoes occuwhen fossils or minerals form, certain unstable elements are sometimes locked into them. the proportion of these unstable elements gradually decreases over time as they decay into other materials in a predictable way. scientists use the rate at which such unstable elements decay to determine when the fossils or minerals formed. the technique described above is known as as

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
