Study Notes
Diffusion
- Diffusion is driven by a concentration gradient, where particles move from an area of higher concentration to an area of lower concentration.
- Diffusion generally occurs from an area of higher concentration to an area of lower concentration, resulting in uniform distribution.
- Diffusion is a passive transport process, meaning it does not require energy input.
- Beyond physics, diffusion is used in fields such as biology, chemistry, engineering, and geology to understand various phenomena.
Diffusion in Spinodal Decomposition
- In spinodal decomposition, the driving force for diffusion is the reduction of free energy, which occurs when the system segregates into distinct phases.
