Question

In which direction do molecules move in diffusion?

Answer 1

Diffusion:

1. Diffusion is the term used to describe the movement of molecules along a concentration gradient.
2. It is a significant process that all living things go through.
3. Diffusion is the process by which molecules move from a region of high concentration to a region of low concentration along a concentration gradient.
4. It doesn't take energy for molecules to move down a concentration gradient; this is a natural process.
5. The following lists a few real-world instances of diffusion:
   1. The aroma of incense or perfume.
   2. The CO₂ diffuses in the air when the bottle of soda or cold drinks is opened.
   3. Tea in hot water will diffuse when tea bags are dipped in it.
   4. Air pollution is caused by tiny dust or smoke particles that disperse into the atmosphere.
