Describe diffusion.
Diffusion is the homogeneous distribution of a substance over a surface or within a substance.
What varieties of diffusion are there?
Passive diffusion and active diffusion are the two types of diffusion. Active diffusion requires energy to operate, whereas passive diffusion does not.
What is a diffusion example?
Diffusion may be seen in the entry and departure of gases across cell membranes. When oxygen diffuses into the cell, carbon dioxide diffuses out of it.
What elements have an impact on diffusion?
Diffusion is influenced by a variety of factors, including temperature, permeability of the medium, and gradients in concentration of the chemical being diffused.
What is the diffusion equation?
The equation J = -D c, where c is the concentration, D is the diffusion coefficient, and J is the flow, describes diffusion.
