In gases, molecular diffusion is dependent on pressure and temperature. The higher the pressure, the slower the diffusion takes place, and the higher the temperature, the faster the diffusion takes place. In liquids, an increase in temperature increases the rate of diffusion. However, since liquids are incompressible, the rate of diffusion is ...

Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
