I'm just undergoing Brownian Motion

Aerosol particles share energy with gas molecules and exhibit Brownian motion.

According to kinetic theory, the temperature, pressure, mean free path, and viscosity of a gas are manifestations of the motion of the gas molecules. ... temperature is a measure of the kinetic energy of the molecules, pressure comes from the force of molecular impacts on the container walls, viscosity represents the transfer of momentum by molecular motion, and diffusion is the transfer of molecular mass.

The basic assumptions of kinetic theory are that (1) gases contain a large number of molecules, (2) the molecules are small compared with the distances between them, and (3) the molecules are rigid spheres travelling in straight lines between elastic collisions. Molecules lead a simple, but happy, life in which collisions with other entities are their only means of expression.
