How to calculate the time needed for a perfectly spherical balloon with radius R to become R/2 due to diffusion of the gas inside, which is assumed to be nitrogen, by using Fick's Law of diffusion. Let the Young's Modulus be E.(adsbygoogle = window.adsbygoogle || []).push({});

Fick's First law: J=-D∂C/∂x

the change in pressure result to the change of the thickness of the balloon surface, which implies the diffuse distance will change, but i have difficulty on linking this together.

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
