Why are the three Laws of Thermodynamics so important? Our concept of "Modern Science" is based on a series of major discoveries that define our understanding of the universe. The Laws of Thermodynamics are important because they control interactions of everything in the universe - regardless of scale. These rules stretch across every form of science known to humankind. T o understand the same lets see the Classical physics, so, from a certain perspective, it is entirely based on Newton's Laws of motion. Most of the equations and principles taught in physics are based on these simply stated rules. In a similar way, thermodynamics is defined and based on the fundamental principles known as the Laws of Thermodynamics. All of the equations and guidelines used to design engines, analyze machines, and understand natural phenomena are subject to these laws. The Laws of Thermodynamics tak...
