Look on the hoses and gaskets to find from where the fluid could be leaking. Add power steering stop leak additive to your power steering fluid. Lucas Power Steering Stop Additive is 100 percent guaranteed to stop seal leaks. In older cars, the seals shrink, causing leaks.
Diffusion is the net movement of molecules or atoms from a region of high concentration with high chemical potential to a region of low concentration with low chemical potential.
Diffusion refers to the net movement of molecules from higher to lower concentration. Diffusion may be a simple diffusion or . A simple diffusion is one in which that occurs unassisted. Facilitated diffusion in contrast is an assisted diffusion in a way that it requires a carrier molecule. For instance, polar molecules diffuse across a cell membrane through carrier molecules in the cell membrane.
