Problem 2.237

How will a diffusion coefficient DD and the viscosity coefficient η\eta of an ideal gas change if its volume increases nn times: (a) isothermally; (b) isobarically?

Reveal Answer
2.237. (a) DD increases nn times, η=\eta= const; (b) DD increases n3/2n^{3 / 2} times, η\eta increases n\sqrt{n} times.
