termodinàmic
Termodinàmic is a branch of physics that deals with heat, work, temperature, and energy, and their interrelationships. It describes the laws that govern energy transformations in macroscopic systems. The field is founded on several fundamental principles, including the laws of thermodynamics. The first law, also known as the conservation of energy, states that energy cannot be created or destroyed, only transferred or changed in form. The second law introduces the concept of entropy, stating that the total entropy of an isolated system can only increase over time, or remain constant in ideal cases where the system is in a steady state or undergoing a reversible process. The third law defines the absolute zero of temperature, stating that the entropy of a system approaches a constant value as the temperature approaches absolute zero. Thermodynamics is crucial for understanding a wide range of phenomena, from the operation of engines and power plants to chemical reactions and the behavior of biological systems. Its principles are applied in fields such as engineering, chemistry, materials science, and atmospheric science. The study of thermodynamics provides a framework for analyzing and predicting the feasibility and efficiency of energy conversion processes.
