The thermodynamic laws are fundamental principles that describe how energy moves and changes form in physical systems. The first law, known as the law of energy conservation, states that energy cannot be created or destroyed, only transformed. The second law introduces the concept of entropy, indicating that energy transformations are not 100% efficient and that systems tend to move towards disorder over time. The third law of thermodynamics states that as the temperature of a system approaches absolute zero, the entropy approaches a minimum value. These laws are essential for understanding processes in various fields, including physics, chemistry, and engineering.
