Fundamentals of Thermodynamics Are Applied In These Things

Summary: Thermodynamics studies the properties of heat transfer, and it is applied in several gadgets and the human body. From sweating to refrigeration, thermodynamics is applied everywhere.

Thermodynamics is a combination of two terms, ‘thermal’(heat) and ‘dynamics’ (study). It is the branch of physical science that deals with the relation between heat and other energy forms. Also, it applies to a various scientific topics like chemistry, physics, and engineering. If you think thermodynamics is only limited to your textbooks, you must read this post to know its application.

Laws of thermodynamics

Thermodynamics law involves the Zeroth law, first law, and second law. The third law of thermodynamics is classed as Boyle’s law and Charles's law. The third law unravels many materials as well as spiritual mysteries of nature. It is related to another term known as entropy that helps to understand the existence of human life.

Applications of thermodynamics

Heat engines:According to the law of thermodynamics, heat flows from higher temperatures to lower temperature. It applies to all types of heat engines like Otto, Diesel, and others.  Because of thermodynamics, we are able to design the engines for modern vehicles. Earlier, steam engines also work with the same principles.

Refrigeration: Refrigerators and air conditioners work on the thermodynamics principles based on Reversed Carnot Cycle. If you want to transfer heat from an object at a lower temperature to a higher temperature, external work is required. In the Reversed Carnot Cycle, work is provided to transfer heat from a lower temperature reservoir to a higher temperature reservoir. In refrigerators or air conditioner, it is the compressor which acts as the external agent. The air conditioner or refrigerator removes the room heat and maintains a lower temperature by throwing the absorbed heat into the atmosphere.

Sweating in a crowded place: While walking in a crowded market, you often sweat. No matter how good the climate is, sweating troubles you a lot. In a crowded place, our body cools down by transferring body heat to sweat. Sweat evaporates, adding heat to the room because the first and second thermodynamics law comes into the action. One thing you need to keep in mind that heat is transferred, attaining equilibrium with maximum entropy.

Ice cube melting: Ice cubes dissolve and are absorbed by drinking water or juice. After some time, if we forget to drink, it again attains room temperature by absorbing the atmospheric heat. All these things happen due to the first and second laws of thermodynamics.

Conclusion

Thermodynamics is applicable in various heat transfer gadgets like compressors, steam engines, etc. These applications cannot be underestimated; scholars must know its importance and be well-versed in its concepts.
