Gel formation

Gel formation occurs when a liquid contains molecules that spontaneously connect through internal bonds, creating a network that traps the liquid inside. This network gives the substance a semi-solid, gel-like consistency. Think of it as a three-dimensional mesh where the particles link together, preventing the liquid from flowing freely. Gels can form through chemical reactions, physical interactions, or cooling of certain materials. Common examples include gelatin desserts, aloe vera, or certain medicines. The strength and stability of a gel depend on how tightly and extensively these molecules bond within the substance.
