Give 4 factors affecting osmosis
1) Concentration gradient: the larger the difference in solute concentration between two solutions, the greater the rate of osmosis will be.
2) Temperature: higher temperatures increase the kinetic energy of the water molecules, making them move more quickly and increasing the rate of osmosis.
3) Pressure: applied pressure can either increase or decrease the rate of osmosis depending on which direction the pressure is applied.
4) Permeability of the membrane: the more permeable the membrane is to water, the greater the rate of osmosis will be. Factors that affect membrane permeability include the size and charge of the solute molecules, as well as the lipid composition of the membrane itself.
