This was due to the fact that there was a high concentration of ammonium hydroxide on the cotton wool, yet a low concentration of ammonium hydroxide on to the red litmus paper. Finally, if movement in one direction equals movement in the other direction then dynamic equilibrium occurs Enger, Ross, and Baileyp.

Romeo characteristics essay enjoyment of picnic essays henri matisse essay writing my city in the future essay Two days later the entire tube had changed colour from pink to blue, thus proving that diffusion had occurred.
If the ammonia would have been left in the tube for 24 hours then the concentration of ammonia hydroxide would have been evenly spread inside. The difference in concentration of molecules over a distance is known as a concentration gradient Enger, Ross, and Baileyp.
This simulation is unlike the others because there is now a restriction placed on the molecules. Diffusion is the process in which particles move from an area of high concentration to an area of low concentration in order to evenly spread out.
Equally important, molecular speed is also dependent on the size of the molecule. Furthermore, net movement relates to the movement of molecules in one direction minus the movement of molecules in the other direction. About five minutes later the second red litmus paper in line had also changed from pink to blue.
This process occurs without the presence of energy, although it does eventually result in the release of energy, and can in fact be used to perform certain tasks.

This was due to the fact that there was a high concentration of ammonium hydroxide on the cotton wool, yet a low concentration of ammonium hydroxide on to the red litmus paper. Photo by sirdle Definition Diffusion is the random spreading of particles from areas with higher concentration to areas with lower concentration.
This report looks at four simulations attempting to solve the problem presented, how do the molecules know which way to diffuse? If observing the potato in solution A there is a clear increase in the potatoes weight, that is because there was no partially permeable membrane in that solution so the water was able to easily diffuse into the potato.
If looking at the potatoes used in solutions B and C there was a considerable rise in the potato in solution B yet a smaller rise in the potato in solution C. Osmosis and diffusion compare and contrast essays 5 stars based on reviews.
Animals need oxygen to live and the way the oxygen gets transported throughout their bodies is diffusion.
The osmosis experiment examined the diffusion rates of molasses bags submerged in water of varying temperatures. The diffusion experiment examined two dyes of different molecular weights at different temperatures.
After inhaling oxygen the animals body produces carbon dioxide as a by product, so now the animal has a high concentration of carbon dioxide yet the air has low concentration of carbon dioxide so the carbon dioxide moves from an area of high concentration the animal into an area of low concentration the air.
