Question

As a result of a certain process the viscosity coefficient of an ideal gas increases α = 2.0 times and its diffusion coefficient  β = 4.0 times. How does the gas pressure change and how many times?

Answer 1

We know

Thus η changing α times implies T changing α² times. On the other hand

Thus D changing β times means T^3/2/p changing β times 

So p must change α³/β times.
