Advantages And Disadvantages Of A Fluidized Bed Reactor

Cells and molecules in the environment are constantly moving and changing, for cells to function properly there is a need for equilibrium to be met. The size of the cell and the solution outside of the cell affects the rate of diffusion and osmosis in the cell. Cells are constantly trying to reach an equilibrium with the molecules and substances around it, which is why there are such terms as: hypertonic, hypotonic and isotonic. The procedures allowed testing of whether or not surface area or volume increased diffusion and how different substance control diffusion. Cells are constantly moving to reach equilibrium through diffusion and osmosis.

2. Explain your observations in detail in terms of concentration gradient, diffusion, osmosis, osmotic pressure, passive transport, and active transport.

I will share my newfound knowledge through this paper and I will discuss my finding with my peers and other people who enjoy chemistry. We have been discussing both water displacement and density in class; I assume the relevancy of this lab was to help people who learn better kinesthetically a chance to learn the material in a way they learn best.

2. Describe on way in which osmosis is similar to simple diffusion and on way in which is different.

Whenever a monolayer is attached to a metal surface, the wetting properties and behavior can be significantly affected (Yuan & Lee, 15). In practice, densely-packed self-assembled monolayers (SAMs) can be used to modify the macroscopic properties of a solid surface (Dilimon et al. 202). Changes in wetting properties occur due to changes in the angle made by a liquid droplet whenever it is in contact with the surface. This phenomenon is significant in several contexts for example, in industrial contexts: this property is used to evaluate the cleanliness of semiconductor wafers. In such contexts, contact angles measurements are widely used. Control of this property is also useful during penetration of insecticides or pesticides into plants, and waterproofing of materials (Yuan & Lee, 25). While the former focuses on maximization of wetting, the latter case seeks to minimize liquid-induced wetting (Yuan & Lee, 28).

Under normal circumstances, interstitial fluid, water, and other small solutes can cross the capillary wall, although blood cells cannot.

The purpose of this experiment was to see if a penny could hold more drops of salt water or tap water. It was found that a penny could hold an average of 22.3 drops of tap water and only 20.8 drops of salt water. These results are consistent with the hypothesis: If the salt concentration of water impacts the amount of water a penny holds, then the penny will hold less drops with salt water. While dropping the water onto the penny, it was observed that the water formed into a dome-like shape on the penny. It looked like the individual drops of water turned into one large drop of water. This was observed for both the tap and salt water. This happened due to the cohesion and surface tension of water. Cohesion simply means that water molecules are attracted to each other and want to cling together. Surface tension is the special term that is applied to the cohesion of water molecules.

Aim: To plan and carry out an investigation to show the relationship between volume/Cm3, surface area, and diffusion using agar cubes measured in time/s; and to demonstrate, using diffusion, why the size of cells is limited, keeping the room temperature and pressure constant.

1. What two parameters are responsible for creating the movement (filtration and reabsorption) of fluid across the capillary wall?

must always follow the surface coating rules and guidelines that has to formulated on a basis of

Check step 3 cause open study says: The last calculation where you calculated the volume of the sphere is off, my calculator says it is 1436026.66667, and your number got smaller by multiplying by 4/3. Somehow xD and if it is quarter sized does that mean 1/4 of a sphere

The following hypothesis was made in regard to effect of the concentration gradient on the rate of diffusion: The higher the concentration gradient, the faster the rate of diffusion.

2. Describe what was initially observed when several drops of water were added to several granules of sand initially, and in 2–3 minutes? When drops of water were initially added to sand the water didn’t move of absorb the sand. After about two to three minutes the sand shifted to the outer areas of the water capsule and remained unchanged.

For diffusion and Gas Exchange to occur here they have to have a large surface area dependent on the size of the

The lid-driven cavity flow is most probably one of the most studied fluid problems in the
