Have you ever thought about how reactions take place? It is only due to these laws of thermodynamics. You have heard about this term. But still, you must be in a state of confusion. To avoid this confusion, here we’ll discuss three laws of thermodynamics about a system and its surroundings. These laws express scientific facts and define physical quantities like temperature, heat, thermodynamic work, and entropy.\u00a0<\/span><\/p>\n

But before knowing these laws of thermodynamics, let’s understand thermodynamics first.<\/span><\/p>\n

What is Thermodynamics?<\/strong><\/h2>\n

A branch of science that deals with the study of heat and temperature are what we call as thermodynamics. It relates to other forms of energy. Also, it applies to a variety of science and engineering such as chemical, physical and mechanical engineering. For improving the efficiency of steam engines, thermodynamics was developed.\u00a0<\/span><\/p>\n

Traditionally, there three laws of thermodynamics: First, Second, and Third. The ‘zeroth law’ came later on. Besides this, it involves <\/span>Boyle’s Law and Charles Law<\/a><\/strong>, along with various properties. Let’s know more about these laws.\u00a0<\/span><\/p>\n

Zeroth Law<\/strong><\/h3>\n

Zeroth law states that if two bodies are in thermal equilibrium with a third body, they are also in equilibrium.\u00a0<\/span><\/p>\n

First Law\u00a0<\/strong><\/h3>\n

The first law of thermodynamics is a version of the conservation of energy. It states that the total energy of an isolated system is constant.\u00a0<\/span><\/p>\n

Thus it can neither be created nor be destroyed. It cn only transfer from one form to another.\u00a0<\/span><\/p>\n

Second Law\u00a0<\/strong><\/h3>\n

The second law of thermodynamics involves the irreversibility of natural processes. It states that the entropy of any isolated system always increases and never decreases.\u00a0<\/span><\/p>\n

Third Law<\/strong><\/h3>\n

The third law states that a system’s entropy approaches a constant value as the temperature approaches absolute zero.\u00a0<\/span><\/p>\n

That means, at zero temperature, the system will have minimum thermal energy.\u00a0<\/span><\/p>\n

Applications of Thermodynamics<\/strong><\/h2>\n
