Osmotic pressure

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane.It is also defined as the measure of the tendency of a solution to take in a pure solvent by osmosis. Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from its pure solvent by a semipermeable membrane. Osmosis occurs when two solutions containing different concentrations of solute are separated by a selectively permeable membrane. Solvent molecules pass preferentially through the membrane from the low-concentration solution to the solution with higher solute concentration. The transfer of solvent molecules will continue until equilibrium is attained. (Wikipedia).

Show Me Some Science! Can Crush

A metal can and a hose are filled with water, and the hose is lowered off of a second floor balcony. The water drains and the can is crushed! In a fluid, like air or water, the pressure is always greater on the bottom than on the top. This is because the weight of all of the fluid pushes
