Diffusion time increases with the square of diffusion distance. The diffusion coefficient is unique for each solute and must be determined experimentally. It is a function of a number factors including molecular weight of the diffusing species, temperature, and viscosity of the medium in which diffusion occurs.
The average kinetic energy of the molecules is 5.66 × 10⁻²¹ J. According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature. The formula is KE = 3/2kT where T is the Kelvin temperature and k is Boltzmann's constant.
height and the decrease in the molecular weight of air with height. Equations (3a) and (3b) were developed in reference 2, which includes tables of pressure-altitude values based on these equations. In the pressure-altitude tables of the present paper, the altitudes are give in geopo-tential meters.

The mass of one mole of a substance is equal to that substance's molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams. Key Terms. mole: The amount of substance of a system that contains as many elementary entities as there are atoms in 12 g of carbon-12.
