👉 Diffusion is a concept in physics that describes the movement of particles or molecules through a substance. It involves the random motion of these particles, which can be influenced by various factors such as temperature, pressure, and chemical composition. In chemistry, diffusion refers to the movement of substances from one area to another without the aid of any external forces. This process is crucial for many biological processes in organisms, where nutrients are transferred between different parts of the body. Diffusion has a wide range of applications across
