What are the differences between diffusion and osmosis?

substance, condition and presence of membranes are the main differences between diffusion and osmosis. Diffusion includes the movement of particles from the area of ​​high concentration into the lower concentration area. Osmosis is a type of diffusion, but only includes water movement across the semipermeable membrane from an area containing low solut concentration into an area containing a high concentration of solut.

Diffusion and osmosis are forms of passive transport in which the system does not require energy. During this process, this process can occur with any substance in any condition, including solids, liquids and gases. For example, the helium released from the balloon can distract by air, while a drop of dye in the water will gradually disperse throughout the container. The solids may take diffusion, as in the case of sodium chloride dissolution and water scattering. Experiments have also found that solids can be distracted to Oerseds, but this cannot be easily observed because the diffusion rate is much slower than the measures of liquids and gases.

osmosis only describesthe movement of water. Specifically, this includes water diffusion through a semipermeable membrane such as a cell membrane. Osmosis also requires water to be in a liquid state rather than on solid ice or gaseous water.

During the process of osmosis, water is considered to be a solvent molecule and all other substances are considered to be solutes. Water travels from an area containing low volumes over the membrane to an area with a higher amount of solut. In general, the soluts are separated by a membrane that remains permeable for water, but impermeable for solut materials, which means they cannot pass through it. Diffusion and osmosis differ in this way because the diffusion describes the movement of the soluts through Solvent, while osmosis describes the movement of the solvent itself.

Another difference between diffusion and osmosis includes the fact that osmosis must run above the membrane, while diffusion can occur anywhere in any size.Osmosis also often occurs at a slower speed than on average diffusion, as diffusion includes a smooth movement that is much faster than liquid movement. Diffusion also observes the movement of particles in any direction, while osmosis focuses only on the movement of water in one direction through the membrane.
