### Step-by-Step Solution: 1. **Understanding Physisorption**: Physisorption, or physical adsorption, is a process where gas molecules adhere to a solid surface through weak van der Waals forces. This process is generally reversible. 2. **Nature of Physisorption**: Physisorption is an exothermic process, meaning that it releases heat when gas molecules are adsorbed onto a surface. The energy released during this process is due to the formation of weak interactions between the adsorbate (gas) and the adsorbent (solid). 3. **Desorption Process**: The reverse of physisorption is desorption, where the adsorbed molecules leave the surface. This process is endothermic, meaning it requires energy (heat) to occur. ...
