Choose one of the Laws of Thermodynamics (zeroth, first, second, or third) and give a brief summary of its development.

Who is credited with "discovering" it and when?
How did the four laws come to be ordered as they are?
Please explain in detail

The second law of thermodynamics describes the concept of entropy and the direction of natural processes. It states that in any spontaneous process, the total entropy of a closed system and its surroundings always increases, or at best remains constant.

The second law of thermodynamics was developed by multiple scientists over time, but it was primarily formulated by Rudolf Clausius and Lord Kelvin (William Thomson). Clausius, a German physicist, introduced the concept of entropy in 1850 and proposed that in isolated systems, heat spontaneously flows from higher temperature regions to lower temperature regions. He articulated this principle in terms of energy conservation and heat transfer. Lord Kelvin later expanded on Clausius' work and provided a mathematical formulation of the second law, suggesting that it is impossible to convert all heat into work without a net decrease in available energy. Both Clausius and Kelvin made significant contributions to our understanding of the second law and are credited with its development.

The ordering of the four laws of thermodynamics, specifically the zeroth, first, second, and third laws, is based on the historical progression of their concepts and their increasing complexity:

1. The zeroth law of thermodynamics, sometimes referred to as the law of thermal equilibrium, was stated later than the rest of the laws. It was introduced by Ralph H. Fowler in the early 20th century. This law asserts that if two systems are each in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other.

2. The first law of thermodynamics, often referred to as the law of energy conservation, was formulated by Julius Robert von Mayer, James Prescott Joule, and Hermann von Helmholtz between the mid-19th and early 20th centuries. This law states that energy cannot be created or destroyed in an isolated system, but it can only be converted from one form to another.

3. The second law of thermodynamics, as mentioned earlier, deals with the concept of entropy and was primarily developed by Clausius and Lord Kelvin in the mid-19th century.

4. The third law of thermodynamics, developed by Walther Nernst in the early 20th century, addresses the behavior of systems as they approach absolute zero temperature. It states that the entropy of a perfectly crystalline substance approaches zero as its temperature approaches absolute zero.

The ordering of the laws is based on their historical evolution and increasing understanding of thermodynamics principles. The zeroth law establishes the concept of temperature and thermal equilibrium; the first law focuses on energy conservation; the second law introduces the concept of entropy; and finally, the third law addresses the behavior of substances at extremely low temperatures.
