How diffusion could be determined

WebDiffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air. For example, think about someone opening a bottle of perfume in a room filled with people. WebJul 30, 2024 · Diffusion is the movement of a substance from an area of high concentration to an area of low concentration due to random molecular motion. All atoms and molecules possess kinetic energy, which is the energy of movement. ... Ultimately, the tonicity of a solution can be determined by examining the effect a solution has on a cell within the ...
