Discover the Zeroth Law of Thermodynamics —its definition, significance, and how it underpins temperature measurement and thermal equilibrium. The zeroth law of thermodynamics is one of the four laws of thermodynamics , which states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with one another. Thermodynamics is the study of the relationship between heat, temperature, work, and energy. The Zeroth Law of Thermodynamics , the First Law of Thermodynamics , the Second Law of Thermodynamics , and the Third Law of Thermodynamics are the four laws of thermodynamics . The zeroth law of thermodynamics was created after the first three, which is an important distinction. However, there was considerable debate over whether it should be known as the fourth law or by another name. The problem arose because the new law effectively replaced the previous three statutes and gave a clearer ...
