termicas

Termicas, sometimes rendered as thermics in English, is a broad concept used to describe phenomena, systems, and materials related to heat and thermal energy. In science and engineering, termics encompasses the study of heat production, transfer, storage, and utilization, and is closely linked to thermodynamics and heat transfer theory.

Core topics within termicas include the mechanisms of heat transfer—conduction, convection, and radiation—and the principles of energy balance, temperature, heat capacity, and phase changes. Calorimetry and thermometry are used to measure thermal properties and processes, while the study of materials focuses on thermal conductivity, insulation, and phase-change materials for energy storage. The field also considers practical aspects of design and control for devices and systems that manage heat.

Applications of termicas span a wide range of technologies. These include heating and cooling systems for buildings, industrial processes that require precise temperature control, and power generation, including thermal power plants and cogeneration schemes. Solar thermal technologies and various forms of thermal energy storage (sensible, latent, and thermochemical) are also part of the domain. Cryogenics and high-temperature engineering represent more specialized areas where thermal considerations are critical.

In measurement and instrumentation, termicas relies on tools such as calorimeters, thermocouples, resistance temperature detectors, and infrared thermography. While the term is used in some languages and contexts, English usage often favors thermodynamics, thermal science, or heat transfer to describe the field with greater precision.
