1. The concept of gas collisions can be applied to the study of metrology. Being the highest composition in atmospheric air (78% by volume), N2 has a collision diameter of 0.369 x 10° m. At 298 K and 1 atm, calculate the single collision frequency of N2 at sea level. The collision frequency of N2 decreases at higher altitude. At 11 km from the sea level, the collision frequency is 3.16 x 10° s1. Calculate the pressure of the gas at this altitude (T = – 220 K). Determine the mean free path for N2 at the altitude of 11 km (the altitude similar in Question 1.ii.) i. ii. iii.
