regardind osmosis, list and briefly describe the factors that change the slope and curve.

The first thing is that we should understand what is osmosis? It is the transfer of molecules of a solvent passing through a semi-permeable membrane from a lower concentration to a higher concentration. Knowing this let us now look at the factors that affect the osmotic curve:

1. Concentration

The concentration of solutions can affect rate of osmosis and can increase the curve of intake of molecules from the surroundings into the object. For instance if the solution has a higher amount of solvent molecules than the solvent molecules in the object it will move quicker into the object through the semi-permeable membrane, however that being said if the condition were opposite the solution had fewer molecules of solvent than the molecules of the solvent in the object it will transfer solvent molecules from the object to the solution.

2. Surface Area

In osmosis the surface area plays a vital role in determining how quickly the solvent molecules move from the solution into the object. The other factor is the ease at which the solvent molecules can move into the object, if it cannot easily get through the permeable membrane or not during osmosis it will make the curve quicker or slower.

3.Temperature

When there is an increase in the temperature it fastens the rate of osmosis, this is because high temperature gives the particles from the solutions more kinetic energy, therefore they can collide faster and have more successful collusions to give a faster rate of osmosis. Another reason is that the permeability of the semi-permeable membrane increases.
