Does diffusion occur fastest?

Diffusion happens in all states of matter, from solid to liquid to gas. Diffusion occurs the quickest when matter is in its gaseous state. Diffusion is, quite simply, the movement of molecules from a very busy, or "concentrated," area to one of less concentration.

Can diffusion happen at any time?

Osmosis only occurs when a semi-permeable membrane is present, but diffusion can happen whether or not it is present. 3. Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely.

What is needed for diffusion to occur quickly?

Other factors being equal, a stronger concentration gradient (larger concentration difference between regions) results in faster diffusion. ... For example, oxygen might move into the cell by diffusion, while at the same time, carbon dioxide might move out in obedience to its own concentration gradient.

How does diffusion occur?

Diffusion occurs when particles spread. They move from a region where they are in high concentration to a region where they are in low concentration. Diffusion happens when the particles are free to move. This is true in gases and for particles dissolved in solutions - but diffusion does not occur in solids.

Why does diffusion take place?

Diffusion is the process by which particles of one substance spread out through the particles of another substance. ... Diffusion happens on its own when the particles spread out from an area of high concentration , where there are many of them, to areas of low concentration where there are fewer of them.

Which diffusion is the fastest?

Diffusion is the property of matterwhich is based on the motion of its particles. Diffusion occurs in gases, liquids and solids. Diffusion is fastest in gases and slowest in solids. The rate of diffusion increases on increasing the temperature of the diffusing substance.

When can diffusion occur at a faster rate class 9?

The molecules of gas have more kinetic energy than liquid molecules and are smaller. Fluid diffusion is slower because the particles move slower in a fluid. When the temperature is changed, it occurs quicker.

Can diffusion be faster than directed motion?

In either case, active diffusion can be much faster than ther- mally driven random motion.

Why would diffusion not occur?

Explanation: Diffusion is the movement of particles from an area of high concentration to an area of low concentration, as the atoms in a solid are stationary (they vibrate in a regular arrangement due to being the state with the least energy), the particles cannot move and therefore cannot diffuse.

Where does diffusion happen in processing food?

Diffusion of water, salts, and waste products occurs in the kidneys. Diffusion of calcium from food into cells occurs in the intestines. Molecules are not the only things that can diffuse.

Does diffusion occur after equilibrium?

Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, movement of molecules does not stop.

Which conditions would cause diffusion to happen more slowly?

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.

Where does diffusion take place in plants?

Diffusion and the leaf

The higher concentration of carbon dioxide in the air around the plant causes the gas to move into the leaf by diffusion. It diffuses through small pores called stomata. The stomata are mainly in the lower epidermis (the underneath surface) of leaves.

What is diffusion rate?

The rate of diffusion, dn/dt, is the change in the number of diffusing molecules inside the cell over time. Since the net movement of diffusing molecules depends on the concentration gradient, the rate of diffusion is directly proportional to the concentration gradient (dC/dx) across the membrane.
