📖 1. Adhesion and Cohesion

🔑 Key Concepts & Definitions

• Adhesion: The force of attraction between molecules of different substances at their interface, e.g., glue bonding paper.
• Cohesion: The attraction between molecules of the same substance, maintaining its integrity, e.g., water molecules sticking together.
• Colloidal System: A heterogeneous mixture where one substance (dispersed phase) is evenly distributed within another (continuous phase), e.g., milk.
• Ligand: A molecule, ion, or atom that binds to a central atom or ion to form a complex, often in biological or chemical systems.
• Diffusion: The spontaneous movement of molecules from an area of higher concentration to an area of lower concentration across gases, liquids, or solids.
• Phase & Phase Boundary: A homogeneous part of a system that can be separated physically or chemically; the phase boundary is the thin interface separating different phases.
