Overview
Diffusion is a vital process that allows substances to move from areas of high concentration to low concentration, achieving balance within systems. It plays a crucial role in biological functions, such as gas exchange in lungs and nutrient absorption in cells. Understanding diffusion helps explain ...
Key Terms
Example: A high concentration of salt in water means there is a lot of salt in a small amount of water.
Example: When perfume is sprayed in a room, it eventually spreads evenly, reaching equilibrium.
Example: Oxygen entering cells through diffusion is a form of passive transport.
Example: Water is made up of molecules consisting of two hydrogen atoms and one oxygen atom.
Example: The diffusion rate of a gas is faster than that of a solid.
Example: A steep concentration gradient leads to faster diffusion.
