Diffusion is the movement of molecules along a concentration gradient by spontaneous random motion to achieve a uniform distribution.
<h3>What is diffusion?</h3>
Diffusion is the movement of water vapor from regions of high concentration (high water vapor pressure) toward regions of lower concentration.
Diffusion can also be defined as the random movement of molecules (fluids) along a concentration gradient until even distribution is achieved.
Therefore, diffusion is the movement of molecules along a concentration gradient by spontaneous random motion to achieve a uniform distribution.
