Problem 2.230

As a result of some process the pressure of an ideal gas increases nn -fold. How many times have the mean free path λ\lambda and the number of collisions of each molecule per unit time vv changed and how, if the process is (a) isochoric; (b) isothermal?

Reveal Answer
2.230. (a) λ=\lambda= const, vv increases n\sqrt{n} times; (b) λ\lambda decreases nn times, vv increases nn times.
