What is diffusion pressure ?

Text Solution

AI Generated Solution

### Step-by-Step Text Solution 1. **Understanding Diffusion**: - Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. This movement occurs naturally and does not require any external energy, as it follows the concentration gradient. 2. **Characteristics of Diffusion**: - The process of diffusion is passive, meaning it does not require energy input. Molecules move randomly and independently of one another during diffusion. ...
