Pronunciation: [kˌaləɹˈɛsəns] (IPA) 
Calorescence is a word used to describe the emission of heat radiation from a substance or object. The spelling of this word is based on its Latin roots "calor" meaning heat and "escence" meaning emission. The IPA phonetic transcription for this word is /ˌkaləˈrɛs(ə)ns/, with the stress on the second syllable. This word is not commonly used in everyday language but is often used in scientific and technical contexts.
Calorescence is a term used in physics and chemistry to describe the phenomenon of producing light without combustion or incandescence, solely by the action of heat or an increase in temperature. It is a form of luminescence that occurs when a material emits visible light in response to thermal energy. Unlike incandescence, where an object emits light due to its high temperature, calorescence refers specifically to light emission resulting from the increase in temperature rather than the high temperature itself.
The process of calorescence involves the absorption of thermal energy by a material, followed by the excitation of its electrons to higher energy levels. As the electrons return to their ground state, they release the excess energy in the form of light, which typically falls within the visible spectrum. The emitted light can vary in color and intensity depending on the specific properties of the material.
Calorescence is observed in various substances, such as certain crystalline materials, gases, and phosphors. It has applications in different fields including thermoluminescence dating, heat detection, and temperature measurement, as it provides a means of detecting changes in temperature through light emission. Understanding the principles and mechanisms of calorescence can contribute to the development of new technologies and materials for thermal imaging, sensing, and energy conversion.
The heating to incandescence of a body by the convergenc upon it, by means of a lens, of the invisible heat rays.

The word "Calorescence" is derived from the Latin word "calor", which means heat, and the French word "escence", which means emission or process of becoming. Therefore, "Calorescence" refers to the emission or production of heat. The term is commonly used in the scientific field to describe the phenomenon of a substance heating up when exposed to certain forms of energy, such as light or radiation.
