tèrmic

Tèrmic is a term that originates from the Greek word "thermos," meaning heat. It is often used in a scientific context to describe phenomena related to temperature and heat transfer. For example, thermal energy refers to the internal energy of a substance that is associated with the random motion of its atoms and molecules. When an object absorbs thermal energy, its temperature generally increases. Conversely, when it loses thermal energy, its temperature decreases.

The concept of thermal equilibrium is also important. Two objects are in thermal equilibrium if there is no net transfer of heat between them when they are brought into thermal contact. This implies that they are at the same temperature. The study of heat and its relation to other forms of energy, such as mechanical work, is known as thermodynamics. This field explores fundamental laws governing energy transformations and their implications in various physical and chemical processes.

In everyday language, "tèrmic" can refer to anything that provides or retains heat. For instance, thermal insulation is a material designed to reduce heat transfer, commonly used in buildings to keep them warm in winter and cool in summer. Thermal conductivity measures how well a material conducts heat. Some materials, like metals, have high thermal conductivity and are good conductors, while others, like wood or plastic, have low thermal conductivity and are good insulators.
