write some real life examples for diffusion
Answers
You can smell perfume because it diffuses into the air and makes its way into your nose.
Cigarette smoke diffuses into the air.
A few crystals of potassium permanganate in water will diffuse and turn the water purple.
Leave a soda bottle open and the carbon dioxide bubble will diffuse and leave it flat.
Answer:
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.
Soda
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.
Tea
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.
