Question
A tanker truck carrying liquid ammonia overturns, releasing ammonia vapor into the air.
(a) Approximating ammonia, oxygen, and nitrogen as
spheres of equal diameter (3 × 10-10 m), estimate the
diffusion constant of ammonia in air at atmospheric
pressure and 20°C.
(b) Calculate the time required for a 100-m root-meansquare displacement of ammonia from the truck, and
express this time in everyday units (seconds, minutes,
hours, days, or years). The actual time for the ammonia to travel this distance is far shorter because of the
existence of air currents (even when there is no wind).
