write ten diffusion example
Answers
Answer:
- Ever notice how helium balloons slowly lose their lift? That’s because the helium is gradually diffusing from a helium-rich environment inside the balloon to the helium-poor environment of the outside air
- A drop of food coloring in a glass of watercolors the water through diffusion. The dye molecules slowly spread evenly through the liquid, creating one particular shade.
- When perfume (or air freshener, cigarette smoke, or just about any other strongly scented substance) is produced in one part of a room, it spreads to the rest through diffusion. There are fewer of the scent-producing chemicals in the further parts of the room, so the molecules naturally spread out.
- Sodas go flat through diffusion. Air has a lower concentration of that bubbly carbon dioxide than the drink does, so the CO2 molecules depart the beverage and spread into the air.
- Stirring loose tea leaves into hot water (using a teabag includes osmosis as water flows into the teabag) causes the chemicals that make tea to diffuse into the water, producing the all-important beverage.
- Take a deep breath and thank diffusion, because oxygen only gets into your bloodstream when the O2 molecules you breathe in diffuse into deoxygenated blood. Breathing in and out is a mechanical action, not diffusion, but the oxygen actually enters your bloodstream through diffusion.
- Calcium isn’t just for bones. It is vital for all sorts of physical functions, including sending nerve signals and making muscles move. When there’s not enough calcium in your bloodstream, your thyroid gland secretes a chemical causing your bones to release calcium, which then diffuses into your blood and solves the problem.
- It’s hard to get excited about kidneys, but you really do need the things. Kidneys filter dangerous chemicals from your bloodstream through microscopic tubes called nephrons. Nephrons separate blood from waste chemicals and toxins, then reabsorb the water and nutrients in the blood through diffusion. The rest goes through the bladder and out.
- Your liver does all sorts of interesting things, but at the top of the list, it synthesizes proteins. You need those. Your body is made of them. In the process, it produces a potentially dangerous waste product called urea. Thankfully for you and your liver, the urea then diffuses into the bloodstream just upstream of your aforementioned kidneys, where it’s filtered out.
- Being largely made up of water, the human body is in a constant state of diffusing water from one place to another. In fact, the process is so constant and complex that MRIs sometimes focus solely on water diffusion in the body to track and diagnose illnesses.

Examples of Diffusion
The textbook definition of diffusion is the movement of molecules or particles from an area of higher concentration to an area of lower concentration, continuing until equilibrium is reached. The defining quality of diffusion is that it takes place because the diffusing substance exists in a higher concentration in one place and a lower concentration in another. If the substance moves for a different reason, such as pressure or force, that’s not diffusion. To get scientific with it, diffusion means a passive movement of molecules down a concentration gradient.
Here are several real-world, practical examples of diffusion from everyday life. That’s what science is!

Diffusion in Daily Life
Being a universal physical phenomenon, diffusion happens all over daily life. Here are a few notable examples.
Balloons
Ever notice how helium balloons slowly lose their lift? That’s because the helium is gradually diffusing from a helium-rich environment inside the balloon to the helium-poor environment of the outside air.
Food Coloring
A drop of food coloring in a glass of watercolors the water through diffusion. The dye molecules slowly spread evenly through the liquid, creating one particular shade.
Perfume
When perfume (or air freshener, cigarette smoke, or just about any other strongly scented substance) is produced in one part of a room, it spreads to the rest through diffusion. There are fewer of the scent-producing chemicals in the further parts of the room, so the molecules naturally spread out.

Diffusion in the Human Body
Let’s be clear: diffusion runs your body. If it stopped, so would you. Here are five reasons why diffusion is vital in our biology.
Breathing
Take a deep breath and thank diffusion, because oxygen only gets into your bloodstream when the O2 molecules you breathe in diffuse into deoxygenated blood. Breathing in and out is a mechanical action, not diffusion, but the oxygen actually enters your bloodstream through diffusion.

When there’s not enough calcium in your bloodstream, your thyroid gland secretes a chemical causing your bones to release calcium, which then diffuses into your blood and solves the problem.
