Intumesce, spelled /ɪnˈtjuːmɛs/ in IPA phonetic transcription, is a verb that means to swell up or become enlarged due to heat or pressure. The word is derived from the Latin word "intumescere" which means to swell up. The spelling of intumesce is characterized by a prefix "in-" which means "into" and a root word "tumesce" which means to swell. While the term may not be commonly used in everyday language, it is often used in scientific fields such as chemistry and medicine.
Intumesce is a verb which describes the process or action of enlarging, swelling, or expanding due to the absorption of heat or other external stimuli. This term is commonly used in scientific and technical contexts, particularly in chemistry, materials science, and engineering.
When a substance intumesces, it undergoes a substantial increase in volume or size as a result of exposure to heat. This expansion occurs due to the release of entrapped gases or the generation of new gases within the material. The internal pressure from the gas generation causes the material to expand, often forming a foam-like or spongy structure.
Intumescence is a well-known phenomenon that is observed in various materials and applications. It is frequently utilized in fireproofing techniques, such as intumescent coatings, where the material expands when subjected to high temperatures, creating a protective barrier that insulates the underlying surface and slows down the spread of fire.
In addition to its application in fire protection, intumescence can be observed in the swelling of certain polymers, expansion of certain liquids upon heating, or even bloating of certain foods during cooking. The ability to intumesce is often a desired property in specific industries as it can provide insulation, energy absorption, structural support, or act as a barrier against various environmental factors.
Overall, intumesce refers to the act of enlarging or swelling due to the absorption of heat or other stimuli, with implications ranging from fireproofing to material science and cooking.

The word "intumesce" is derived from Latin, specifically from the verb "intumescere". "Intumescere" is a combination of the prefix "in-" (meaning "into" or "upon") and the verb "tumescere" (meaning "to swell" or "to become swollen"). Together, "intumescere" literally means "to become swollen or enlarge". The word "intumesce" has been adopted into English with a similar meaning, referring to a process of swelling or expanding, particularly in the context of fluids or materials.
