what is the difference between diffusion and net diffusion?
12998
There is a difference between diffusion and net diffusion. In a homogeneous material, atoms also diffuse but this motion is hard to detect. ... Net diffusion occurs because, although all atoms are moving randomly, there are more atoms moving away from regions where their concentration is higher.

Explanation: When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.

Diffusion results from random motions of two types: the random motion of molecules in a fluid, and the random eddies which arise in turbulent flow. Diffusion from the random molecular motion is termed molecular diffusion; diffusion which results from turbulent eddies is called turbulent diffusion or eddy diffusion.

Explanation: Simple diffusion is the movement of molecules from an area of higher concentration to lower concentration. ... Osmosis is the movement of water from an area of less concentration of dissolved particles to an area of high concentration, thus equalizing the concentrations on each side.

The main difference between perfusion and diffusion is that perfusion is the delivery of blood to the pulmonary capillaries, whereas diffusion is the movement of gases from the alveoli to plasma and red blood cells. ... Here, the gas exchange of animals occurs through the respiratory membrane of the alveoli of the lungs.

Answer and Explanation: Brownian motion is the movement of the particle not in a fixed direction while in diffusion the particle moves in the direction of high concentration to low concentration.

What is the difference between diffusion and facilitated diffusion? Diffusion is the driving force behind the movement of many substances across the cell membrane. ... Facilitated diffusion is where molecules cannot directly diffuse across the membrane pass through special protein channels.

Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole.

is that diffusion is (physics) the intermingling of the molecules of a fluid due to random thermal agitation while diffusivity is (physics) a coefficient of diffusion; especially the amount of heat that passes through a given area in unit time.

Diffusion refers to the process by which innovations are spread among the members of a social system over time (in your organizations), whereas adoption is a decision of implementing innovations based on knowledge, persuasion of individuals within a given system (e.g. Organizations or enterprises) (see Rogers,1995 for ...

The main difference between the two is that diffusion can occur in any mixture, even when two solutions aren't separated by a semipermeable membrane, whereas osmosis exclusively occurs across a semipermeable membrane.

Whereas facilitated diffusion is a passive process and does not require energy. Active transport uses carrier proteins. Energy is used to change the shape of the carrier protein. Facilitated diffusion uses both gated channel proteins and carrier proteins in transport.

bulk flow. "Bulk flow" is the movement/flow of an entire body due to a pressure gradient (for example, water coming out of a tap). "Diffusion" is the gradual movement/dispersion of concentration within a body, due to a concentration gradient, with no net movement of matter.

Mass transfer is the transport of mass from one place to another. ... The main difference between mass transfer and diffusion is that mass transfer may or may not involve a concentration gradient whereas diffusion does involve the movement of a solute down a concentration gradient.

The motion of molecules is through the semi-permeable membrane in osmosis, whereas in diffusion motion is direct and does not require a semi-permeable membrane. Osmosis undertakes in liquid medium only, whereas the process of diffusion undertakes in any medium (solid, liquid and gases).

Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

Diffusion is when single particles move about and transports its momentum and energy to other particles. Convection is a large movement (in roughly the same direction) of a large mass of particles. For the difference see this. Mixing of a drop of ink in a glass of water is diffusion.
