The law of atmospheres states that the number density of molecules in the atmosphere depends on height y above sea level according to where n, is the number density at sea level (where y = 0). The average height of a molecule in the Earth's atmosphere is given by | yn, (1) dy ye D/,T dy avg |n,G) dy eD/A,T dy (a) Prove that this average height is equal to kT/m,g. (b) Evaluate the average height, assuming the temperature is 10.0°C and the molecular mass is 28.9 u, both uniform throughout the atmosphere.
