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

Calculate the time needed for a perfectly spherical balloon with rahis R to reduce its volume to R/2 due to diffusion by applying Fick's law of diffusion. Assuming the young modulus of balloon is E and the gas filled is nitrogen. diffusion constant of nitrogen is D.
