Atomic diffusion in solids

In material science, diffusion can take place in solid, liquid, and gases. In solids, atomic diffusion can take place with the help of thermally activated and randomly vibrating atoms. The atomic diffusion in solids is complex and very slow in comparison to atomic diffusion in liquids and gases because the interatomic distance between the atoms is smaller in solids as compared to liquids and gases.

A tanker ship is transporting 0.798 kg/m3 of a rare gas in its tank. After the fill-up, the 1.94 m long pipe used to fill the tank was left open for 10.4 hours. In that time, 11.7 x10-4 kg of the gas diffuses out of the tank, almost nothing compared to the original quantity of gas in the tank. If the concentration of that gas in our atmosphere is typically zero, and the diffusion constant of that gas is 2.13 x10-5 m2/s, what is the cross-sectional area of the pipe?

Gaseous hydrogen weakens the mechanical strength of cast iron. this phenomenon often occurs in cast iron pressure vessels containing 100% gas hydrogen. H2 gas dissolves in metallic iron and diffuses into solid non-porous iron by an interstitial diffusion mechanism. H2 gas does not need to penetrate far into the iron to have a negative effect on the mechanical strength of iron. In the present situation, 100% of H2 gas at 1.0 atm and 100°C is contained within a 1.0 m internal diameter and wall thickness of 2.0 cm. The solubility of hydrogen in iron in 100°C is 2.2x10-7 mol of H/g Fe atoms. The diffusion coefficient of atoms of hydrogen in solid iron is 124.0x10-9 cm2 /sec at 100°C. Initially, there are no H atoms in solid iron. How many hours will it take for the hydrogen level inside the iron metal reaches 1.76x10-7 mol H atoms/g Fe at a depth of 0.1 cm from the surface exposed to hydrogen gas?
