How long must the temperature at t2 be maintained

Reference no: EM13305647

A block of material A is placed in closed contact with unlimited supply of material B, after 15 hours at temperature T1, it is observed that atoms of B have penetrated 0.5mm into material A. A separate experiment is performed at at temperature T2 that doubles the diffusion coefficient of B in A. how long must the temperature at T2 be maintained in order for atoms of B to penetrate at 3mm into material A?
