- Diffusion in liquids. Diffusion can also happen in liquids. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed. For example if you drop a little bit of paint into a jar of water the colour will spread slowly through the water.This is by diffusion.Diffusion in liquids is slower than diffusion in gases because the particles in a liquid move more slowly.ou don't have to mix the gases by waving your arms around-it mixes on its own. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases. Diffusion happens quickly in gases.

diffusion cultural diffusion in Science. The movement of atoms or molecules from an area of higher concentration to an area of lower concentration. Atoms and small molecules can move across a cell membrane by diffusion. Compare osmosis.

Biology book1 Diffusion occurs in the lungs of the body in the alveoli. Oxygen diffuses from the alveoli of the lungs into the small capillaries that surround them and carbon dioxide diffus … es in the opposite direction; this is called gaseous exchange and it happens to oxygenate and get rid of the waste carbon dioide.smosis is the diffusion of water across a semi-permeable (or differentially permeable or selectively permeable) membrane. The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.

- Diffusion is the movement of particles from high concentration to low concentration in a substance. This process is essential for life on Earth, allowing for the movement of molecular compounds into and out of the cell. All matter in the universe is in motion, because all molecules are vibrating.

- Diffusion is the net movement of molecules or atoms from a region of high concentration with high chemical potential to a region of low concentration with low chemical potential.

Diffusion Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. Consider two containers of gas A and B separated by a partition. The molecules of both gases are in constant motion and make numerous collisions with the partition.

Diffusion Diffusion. Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen.Diffusion diffusion: The movement of particles (molecules or ions) from an area of higher concentration to an area of lower concentration 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.Particles diffuse down a concentration gradient, from an area of high concentration to an area of low concentration.iffusion. Dissolved substances have to pass through the cell membrane to get into or out of a cell. Diffusion is one of the processes that allows this to happen.

diffusion Also found in: Thesaurus, Medical, Legal, Financial, Encyclopedia, Wikipedia. diffusion. In the process of diffusion of a single solute, a concentration of molecules on one side of a membrane (top) will move through a membrane (center) until there is equilibrium on both sides (bottom).

Osmosis and Diffusion osmosis Osmosis is a special example of diffusion. It is the diffusion of a substance through a semipermeable membrane from a more dilute solution to a more concentrated solution. This process is also passive since no external energy is needed. A semipermeable membrane is a barrier that permits the passage of some substances but not others.

Osmosis and Diffusion Diffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. A good example of diffusion is food colouring.iffusion is the movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.

- Answers. FACILITATED DIFFUSION. In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.ACILITATED DIFFUSION. In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.

Revision:Gcse biology - diffusion Diffusion in plants. Diffusion – The passive movement of particles from an area of high concentration to an area of low concentration For photosynthesis to occur carbon dioxide must diffuse into the leaf (via the stomata) to the cells (especially the palisade cells).

Passive transport Diffusion is the net movement of material from an area of high concentration to an area with lower concentration. The difference of concentration between the two areas is often termed as the concentration gradient, and diffusion will continue until this gradient has been eliminated.

Diffusion Osmosis is diffusion through a membrane. The membrane acts as a barrier between two solutions of different concentration. One substance (usually water) travels from an area of high concentration to one of low concentration. Osmosis can be compared to the examples of diffusion given above involving perfume and ink.

- Diffusion is one of the fundamental processes by which material moves. It is thus important in biology and medicine, chemistry and geology, engineering and physics, and in just about every aspect of our lives. Diffusion is a consequence of the constant thermal motion of atoms, molecules, and particles, and results in material moving from areas of high to low concentration.

Test Bank Of Essentials of Anatomy And Physiology 7th Edition by Martini Bartholomew Diffusion is the chemical & biological process when molecules from a material move from an area of high concentration (where there are lots of molecules) to an area of low concentration (where there are fewer molecules). Diffusion usually happens in a gas or in a liquid. It is possible to see diffusion happening when two liquids are mixed in a transparent container.

In and Out of Cells Very few particles travel the opposite way. The result is a concentration gradient with particles diffusing from an area of high concentration to an area of low concentration. Diffusion occurs in gases and with any substance in a solution.Therefore we can say that the definition of diffusion is as follows: Diffusion: The movement of particles from an area of high concentration to an area of low concentration until they spread out evenly. There are two important rules to remember.1  The larger the particles the slower the rate of diffusion.ery few particles travel the opposite way. The result is a concentration gradient with particles diffusing from an area of high concentration to an area of low concentration. Diffusion occurs in gases and with any substance in a solution.

What is the definition of diffusion? Diffusion is the movement of particles from an area of high concentration to an area of low concentration. Diffusion is not to be confused with osmosis, which is the movement of water through a semi-permeable membrane. However, osmosis is a special case of diffusion. Lighting (as in photography).

THE CHEMISTRY OF MILK Diffusion -the process by which molecules spread from areas of high concentration, to areas of low concentration. When the molecules are even throughout a space - it is called EQUILIBRIUM. Concentration gradient - a difference between concentrations in a space.

What Are the Two Main Types of Diffusion & Osmosis? Facilitated diffusion is the flow of molecules down a concentration gradient, across a membrane, but requires the help of a protein. There are two categories of proteins that assist facilitated diffusion: carrier proteins and channel proteins. Carrier proteins are like taxi cabs in a cell membrane.

Interactive STEM activities,freefor your classroom Explore the role of temperature in the rate of diffusion of a substance. Diffusion is the process of a substance spreading out from its origin. Molecules diffuse through random molecular motion. Diffusion is always happening, even when a system appears to have reached equilibrium, because molecules are always moving. When molecules are heated, they move faster.
