Physisorption

Physisorption, also known as physical adsorption, is a process where molecules adhere to a surface through weak van der Waals forces, including dipole-dipole interactions, hydrogen bonds, and dispersion forces. This type of adsorption is characterized by several key features: 1. **Weak Interactions**: The forces involved in physisorption are much weaker than those in chemisorption (chemical adsorption), which involves the formation of stronger covalent or ionic bonds.
