Essays on Diffusion

Diffusion of a Liquid.

Diffusion is the movement of molecules from areas of high concentration to areas of low concentration. With diffusion no energy is required and it is caused by kinetic energy. The rate of diffusion can be affected by many things including temperature, molecular weight, and movement. To test the rate of diffusion a drop of dark …

The Diffusion of a Cell

When substances are brought in contact with each other they intermix, this property is known as Diffusion. This property of diffusion takes place very rapidly in case of gases and to a lesser extent in case of liquids, whereas solids do not show this process of diffusion with each other. But what we can observe …

The Resting Membrane Potency

Introduction The resting membrane potency ( RMP ) is an electrical potency difference in cells, happening across their plasma membranes. The cytol of the cell is electrically negative in comparing to the environing extracellular fluid, this difference in electrical charge gives rise to the RMP. The RMP is indispensable for the operation of many electrically …

The Process Of Diffusion And Osmosis Biology

This lab was performed to understand the procedure of diffusion and osmosis. First away, to to the full grok the point of this lab, one has to be on familiar footings with the workings of diffusion and osmosis. The random motion of molecules that go from a part of high concentration to a part of …

Introduction: Diffusion is vital to many life functions of a cell, it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion, it is as if a bottle of perfume is opened at …

The Effect of Molecular Weight to the Diffusion Rate of Substances

The Effect of Molecular Weight to the Diffusion Rate of Substances[ 1 ] The consequence of molecular weight to the rate of diffusion of substances had been obtained through agarose-water gel experiment. Drops of the undermentioned dye samples were used as controlled variables: K permanganate, K bichromate and methylene blue. Each dye has a molecular …
