Diffusion is a process that occurs when a substance such as water, molecules, and ions, which are usually needed for various cellular processes, enter and leave cells. The way that cell diffusion happens is by molecules moving from an area of high concentration to an area of low concentration.
People also ask, what causes diffusion to occur?
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient. The kinetic energy of the molecules results in random motion, causing diffusion.
Besides, how does diffusion apply to everyday life?
Examples of Diffusion. Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored. Carbon dioxide bubbles diffuse from an open soda, leaving it flat.
Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. For instance, a gas diffuses very quickly in another gas. An example of this is the way the noxious smell of ammonia gas spreads in air.
