👉 An endothermic system, or a system that is in equilibrium with its surroundings and has an internal energy which increases when it absorbs heat from the surroundings. In other words, an endothermic system can have a temperature increase due to the presence of heat. Endothermic systems are also called warm-blooded organisms because they produce heat through metabolic processes that require energy. This process is known as thermogenesis and is essential for the survival of these organisms in their environment. In summary, an end
