10 Examples Of Diffusion In Everyday Life

Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient. Diffusion is an essential process, which is involved in the different life processes. As mentioned above, it is the net movement of particles, ions, molecules, solution, etc. In all living species, diffusion plays an important role in the movement of the molecules during the metabolic process in the cells.

Example of diffusion

Some examples of diffusion that occurs in our daily life are given below.

  • The smell of perfumes/Incense Sticks
  • Opening the Soda/Cold Drinks bottle and the CO2 diffuses in the air
  • Dipping the tea bags in hot water  will diffuse the tea in hot water
  • Small dust particles or smoke diffuse into the air and cause air pollution
  • Breathing and taking oxygen into the body and diffuses in our blood
  • Transport Of Biomolecules and Minerals in Plants and Animals
  • Sugar gets dissolved evenly and sweetens the water without having to stir it.
  • Removal of Waste Substances and Toxins from Our Body
  • Gas exchange in the lungs
  • Diffusion of waste products, salt and water in the kidneys

Factors affecting diffusion

Listed below are factors affecting diffusion

  • Temperature
  • Area of Interaction
  • Size of the Particle
  • The steepness of the concentration gradient
