INTRODUCTION
Molecules undergo constant motion and move in regions with a higher concentration to a lower concentration and this process is called diffusion. It is where particles make numerous collisions with one another and so with the partition. This movement of the particles causes them to be equally and uniformly distributed throughout, (De et. al, 2010). It can occur in any state of matter. The concentration gradient greatly affects diffusion because of the adjustment of regions of concentrations until it reach the equilibrium thus, it is simply the physical flow of any material.
Diffusion can be applied to our daily lives in different ways. A simple example is our way of breathing. Oxygen is carried in our lungs and diffused into our bloodstream. Another is when you bake cupcakes and the smell of it filled the house by diffusion. The particles inside the microwave which is the higher concentration will spread out into the house because it has lower concentration.
According to Markings, rates of diffusion are affected by several factors and these are medium of diffusion, concentration gradient and temperature. In medium of diffusion, the greater number of molecules or larger particles in the medium, the lower the rate of diffusion because these particles act as a barrier to diffusion. High concentration gradient leads to greater rate of diffusion considering the greater probability of molecular collisions.
One of the main factors that affect the rate of diffusion is the temperature. The higher the temperature, the faster is the rate of diffusion because as temperature increases,
