animation how osmosis works

Solutions..

It is a physical process in which the solvent (water) moves from the region of its higher concentration to the region of its lower concentration across a semi-permeable membrane. This is to say that water moves from a dilute to a concentrated solution. Water is absorbed into the root cells by ..

It is a process involving net diffusion of water molecules from a region of higher water concentration to a region of lower water concentration through a semipermeable membrane. The osmotic movement of water from a surrounding medium into a cell is called endosmosis. Such a medium is described as h..

A thistle funnel, covered at the broad end by a differentially permeable membrane, contains a 10% sugar solution. The beaker contains a 5% sugar solution as shown in fig. a. The solute is unable to pass through the membrane, but the water passes freely through in both directions. The net movement ..

. The human urine contains urea, water, other nitrogenous waste products sodium chloride, mineral salts, some non-nitrogenous organic substances. The urine is primarily formed by the filtration of a protein - free filtrate from the blood of glomerular capillaries into the Bowman's capsule. As the g..

Reverse Osmosis and Water Purification - The osmosis process can actually be reversed if a pressure larger than the osmotic pressure be applied to the solution. This phenomenon has found uses in water purification, especially the desalination of sea water. An apparatus for this ..

Osmosis in a cell can be demonstrated by a potato osmoscope experiment. Peel the skin of a potato and remove the inner contents to form a cup shaped hollow. Place the potato in a container with water. Pour 5% sugar solution in to the potato cup up to a particular level. Pierce a pin to m..

Force Work Power Energy and Machines..

The transference of energy may take place as work if the system and surroundings have different pressures. For e.g., suppose a gaseous system is enclosed in a cylinder fitted with a movable piston. If pressure of the system is higher, the piston will be pushed up until the pressure of th..

H 2 and O 2 are bubbled through a porous carbon rod into concentrated NaOH. Catalysts are present in the electrodes. ..
