Osmosis Introduction Osmosis is the flight of water from a orbit of high water parsimoniousness by dint of a semi-permeable membrane to a region of low water concentration. The arrive of the investigation is to find the variables that go the count of osmosis and how they affect the rate of answer. The variables that affect the rate of reaction of osmosis are, The surface area of the object, The concentration of the solution, Temperature of the experiment egress area If the surface area of the object is larger then much molecules can pass through the semi-permeable membrane. This provide ultimately increase the rate of reaction. IMAGE IMAGE IMAGEIMAGE Small surface area Large surface area preoccupation If the concentration of the solution is high then it will contain to a greater extent molecules and so the rate of reaction will be shorter. IMAGE IMAGE Low concentration High concentration Temperature of the experiment Generally the high the temperature, the less eon it takes for a reaction. But with living cells there is a point at which the cell will be denatured therefore the rate of reaction will be altered, as the cells are no longer functioning. supposal ========== Osmosis is defined as the movement of water or any opposite solutions molecules from a region of highly concentrated solution to a region of less concentrated solution. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through merely does not allow bigger molecules to pass through. The molecules will continue to sonant until the area in which the molecules are found reaches a state of equilibrium, pith that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other. To make this investigation fair, the conditions will be as follows Changed v ariable Constants
