1. Why do molecules move this way? Guiding question:
2. Diffusion Diffusion - the movement of molecules from areas of high concentration, to areas of low concentration caused by the random motion of particles.
When the molecules are even throughout a space - it is called Equilibrium.
Concentration gradient - is a difference between concentrations in a space.
3. Diffusion Requires NO energy
Molecules move from area of HIGH to LOW concentration
4. An Example of Diffusion Molecules of oxygen are represented by the small circles on the diagram to the left.
Which way will oxygen diffuse in this example?
5. Diffusion and Temperature The speed of diffusion depends on several factors, including temperature.
Do think a higher temperature will cause diffusion to occur more rapidly or more slowly?
