Diffusion, the passive movement of particles from an area of high concentration to an area of low concentration. Particles like to move! Because they like to move, they want to spread out as much as possible. Diffusion happens because the particles want to spread into the remaining fluid, (liquid and gas) to an area of low concentration. Another way of thinking, when you spray deodorant, because of the initial pressure that pushes all of the particles out of the can, they spread out in all directions.
The cube is high in concentration and when it dissolves it be comes low in concentration. It diffuses: molecules move from an area of high concentration to an area of low concentration. Hope this helps, It was on my homework too.
When a tea bag and a spoonful of sugar are placed in hot water, diffusion allows the sugar molecules to move from an area of high concentration to a lower concentration throughout the water, sweetening it. Osmosis causes water to move into the tea bag, allowing the flavor compounds to diffuse out and infuse the water.
because it is liquid mixing in to another liquid
The presence of a semipermeable membrane during osmosis allows water molecules to pass through while blocking larger molecules. This causes water to move from an area of higher concentration to an area of lower concentration, balancing the concentration on both sides of the membrane.
The concentration gradient is what causes molecules to diffuse.
Diffusion in a gel is caused by random molecular motion of solute molecules due to differences in concentration. The solute molecules move from areas of high concentration to low concentration, spreading out within the gel matrix. This results in a gradual distribution of the solute throughout the gel.
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
Diffusion is a process that occurs naturally everywhere. All molecules and particles that are in an area of higher concentration in a gas or liquid will tend to move to an area of lower concentration. That is diffusion.
Gas molecules move along a test tube due to diffusion, which is the random movement of molecules from an area of high concentration to an area of low concentration. This process allows the gas molecules to spread out evenly in the available space within the test tube.
The energy that drives diffusion is thermal energy, which causes molecules to move randomly and spread out to achieve equilibrium. This kinetic energy allows particles to overcome barriers and move from areas of high concentration to areas of low concentration until they are evenly distributed.
Diffusion of a gas is best described using Grahams law of diffusion. It states that the rate of diffusion of gas is inversely proportional to the molecular weight of gas. diffusion generally occurs from a region of high concentration to a region of low concentration. Diffusion occurs in liquids , gases . Generally we sense the smell of chlorine when it is leaked , Here chlorine gas is initially in cylinder at a higher concentration and a higher pressure . Now it is diffused in to surroundings where it have lower pressure and lower concentration.
Gases in diffusion move around due to the kinetic energy of their molecules, which causes them to collide and spread out in space. This movement occurs because gas molecules are in constant random motion, and they tend to move from areas of higher concentration to areas of lower concentration in order to achieve equilibrium. Additionally, the lack of strong intermolecular forces in gases allows them to move freely and fill the available volume.
Some nutrients move into a cell of diffusion
Diffusion is caused when molecules are moving around and bumping each other in the cell. Collisions cause the molecules to them push apart from one another. Eventually the molecules continue to do this and they spread throughout the area.

Active transport is similar to diffusion, in that it is the movement of molecules. However, whereas diffusion occurs passively and molecules move from an area of high concentration to an area of low concentration, active transport reverses this. Molecules are transported from an area of high concentration to an area of low concentration, and this requires energy in the form of ATP. Active transport accross a membrane takes place via specific transport proteins. ATP produced in respiration causes these proteins to change their 3D shape when a molecule binds with it, so that it is taken into the cell/transported from the cell against the concentration gradient. An analogy of a kissing gate can be used. So, for example, if the concentration of mineral salts inside a root hair cell is higher than that outside the cell in the soil, then diffusion cannot take place passively as the concentration gradient is not in the right direction. Mineral salts would not passively move from an area of low concentration (soil) into an area of high concentration (cell). In this case, active transport must be employed for the cell to absorb the ions in the soil. They bind to proteins on the cell membrane, which actively "carry" them into the cell using energy from respiration. In this way, the plant can absorb the mineral salts even though the passive diffusion gradient is the wrong way. Active transport can be defined as "the energy consuming transport of molecules or ions across a membrane against a concentration gradient, made possible by transferring energy from respiration."
