Problem 38E

Calculate the mean free path of air molecules at a pressure of .

Step-by-Step Solution:
Step 1 of 3

Solution 38E The expression for mean free path is given by, kT = 2 …..(1), where k is Boltzmann’s constant, T is the temperature in absolute 4 2r P scale, r is the radius of air molecule and P is the pressure. Given, P = 3.50 × 10 13atm 13 5 5 P = 3.50 × 10 × 1.01 × 10 Pa (since 1 atm = 1.01 × 10 Pa) P = 3.53 × 10 8Pa 0 T...
