Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. It can happen in liquids and gases.
In liquids it can be observed when some potassium permanganate crystals are put in a beaker of water and the solution turns purple after a few minutes, the crystals diffuse in the solution
In gases it can be observed when a piece of cotton wool is dipped in hydrochloric acid and another piece of cotton wool is dipped in ammonia, they are put at the ends of a glass tube and a white circle is seen to form closer to the cotton wool with HCl this proves that ammonia diffuses faster than hydrochloric acid, the white solid formed is ammonium chloride.The ammonium chloride is not formed at the centre because ammonia diffuses along the tube at a greater rate than the hydrochloric acid.

Why does diffusion takes place in the leaf?
Diffusion occurs in the leaf to facilitate the movement of gases such as carbon dioxide and oxygen. These gases diffuse in and out of the leaf through small openings called stomata, allowing for photosynthesis and respiration processes to take place effectively. This exchange of gases helps the leaf to obtain the necessary substances for energy production and to release waste products.
What term refers to the movement of molecules from a higher concentration to an area of lower concentration?
Diffusion, a form of passive transport, is the movement of molecules from an area of greater concentration to an area of lower concentration. Osmosis is a special case involvement the movement of water from an area of higher concentration of water molecules to an area of lower concentration of water molecules. It takes place in all three states of matter-Solids, liquids and gases.
Are effusion and diffusion are two ways that gases mix with other gases?
Yes, effusion and diffusion are two ways that gases mix. Effusion is the process where gases move through a small opening, while diffusion is the process where gases mix by moving from areas of high concentration to areas of low concentration. Both processes play a role in the overall mixing of gases.
What factors the rates of dffusion?
Temperature, initial concentration, and the medium in which diffusion takes place (solid, liquid, or gas).
What type of process takes place if the hydrogen ions move without the help of additional energy?
Facilitated diffusion
What is the process by which the exchange of gases takes place?
Diffusion.
Diffusion can take place if the two substances are?
Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
Why exchange of gases occur more efficently in air than in water?
Because in air the diffusion of gases takes place more quickly than in water.

Where in your body does diffusion take place?
diffusion takes place in the alveoli
What happens in gaseous exchange?
The diffusion of gases takes place from their higher concentration to lower concentration. Exchange of oxygen by carbondioxide is the usual feature of breathing by lungs.
Which blood vessel does diffusion of oxygen and carbon dioxide take place?
Diffusion of oxygen and carbon dioxide takes place primarily in the capillaries, which are the smallest blood vessels in the body. Capillaries have thin walls that allow for the exchange of these gases between the bloodstream and the surrounding tissues.
When two gases are mixed what is it called?
When two gases are mixed together, it is referred to as a gas mixture. This is because the gases are physically combined, retaining their individual properties without a chemical reaction taking place.
What are stomata and what are they?
exchange of gases takes place by simple diffusion directly into each cell through the openings present in epidermis called stomata. Stomata are found on the underside of leaves. :)
Where does diffusion takes place?
In a cell in the human body diffusion takes place in the cell membrane. The cell membrane allows smaller sized molecules to pass through.
Diffusion takes place?
From an area of high concentration to and are of low concentration
Does the diffusion of respiratory gases take place at the membranes between the alveolar ducts and lymphatic capillaries?
no
