Question

what is diffusion? give an example from the daily life to show that how diffusion occurs​

Answer 1

Answer:

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.

IF WE LIT AN INCENSE STICK(AGARBATTI) IN A ROOM, WE WILL OBSERVE THAT AFTER SOMETIME WE CAN SMELL THE FRAGRANCE OF IT ALL OVER IN THE ROOM. THIS IS DUE TO DIFFUSION.

Answer 2

Answer:Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states

For example, oxygen is at a higher concentration inside arteries and arterioles, when compared with the oxygen levels in actively respiring cells. By the time blood flows into capillaries in the muscle or liver, for instance, there is only a single layer of cells separating this oxygen from hepatocytes or skeletal muscle fibers. Through a process of passive diffusion, without the active involvement of any other molecule oxygen passes through the capillary membrane and enters cells.
