Chemistry: Diffusion topic


The independent mixing of particles of different substances is called diffusion. Diffusion occurs because the particles of all substances move and this movement of the particles leads to a gradual mixing.

Diffusion

If you put a few drops of ink in a glass of water, the ink will gradually spread itself throughout the water. The warmer the water, the faster it happens - chemistry helper . The ink spreads because the particles of water and ink are in constant motion.

If you add sugar to hot tea, the entire tea tastes sweet after a while. Sugar particles and water particles gradually mix. 

The smoke from cigarettes or the smell of perfume gradually diffuses into a room.

The independent mixing of particles of different substances is called diffusion.

Diffusion occurs because the particles move and this movement of the particles leads to gradual mixing (also english home work help will be useful for you). Diffusion is thus evidence of the movement of particles and thus also evidence of the particle model . 

Diffusion is particularly pronounced in gases and liquids. But it is also possible with solid bodies. This is used, for example, to manufacture semiconductor materials . 

Diffusion also plays an important role in the uptake of water by plants. The diffusion that occurs through semi-permeable membranes is known as osmosis .
