Question 61
XE-CNAT2 marksNeeds review
It is known that component A diffuses into a solid to a depth of 10 μm in 1 hour at 300 K. Treat diffusion in one dimension. The time taken for A to diffuse to the same depth at 600 K is ________ seconds. (Round off to 1 decimal).
Diffusivity of A in the solid is given by
: Diffusivity coefficient
: Activation energy = 0.3 eV
: Boltzmann’s constant = 8.62×10⁻⁵ eV/K
: Absolute temperatureLog in to check the answer
