Product Description
Diffusion is the passive movement of molecules from one area to another area, without the need for energy. When molecules move because of diffusion, we say that they diffuse. This movement is always from an area of high concentration (where there is a lot of that molecule) to an area of low concentration (where these is not a lot of that molecule) until the molecule is evenly distributed throughout the area. This idea of diffusion explains the movement of all types of things based on concentration within a material or solution, or even within your own body. This is same concept that explains why the powder drink mix will eventually spread through the entire glass of water. If you’d be willing to give it enough time to do so.
Even though the process does not require energy. If the environment that is being studied has more energy within it (warmer) the rate at which diffusion takes place should be warmer. The opposite should hold if the environment is cooler. In this experiment you will test this concept based on the rate at which a color dye will be able to passively move through solutions of different temperature.
