Summary
This document describes the process of diffusion in liquids and gases. It explains how molecules move from higher concentration areas to lower concentration areas, and how the steepness of the concentration gradient affects the rate of diffusion. Molecules spread out evenly until evenly distributed.

Diffusion liquids and gases are composed of tiny particles called molecules. These have energy and are always moving about in random directions. As a result of this movement this spread out to fill the space available. Diffusion is the movement of molecules from a region where they are in in a higher concentration to a region where they are in a lower concentration until they are eventually distributed. Diffusion in gases can be shown using bromine. At room temperature bromine is at orange, brown volatile liquid. If you pour some of this liquid into a gas and invert another gas jar over the top, the liquid bromine vaporizes, and the gases molecules diffuse and spread into the upper gas jar. A diffusion or concentration adding it refers to the difference in concentrations and monocules in two areas. If there is a steep concentration gradient in the molecules will diffuse from the area of higher concentration area of lower concentration at a rapid rate. Get the concentration gradient is less steep the rate of diffusion will be slower.
