The Most Important Thermodynamics Law
There are four laws of thermodynamics in physics, each describing unique aspects of heat transfer. The laws include the postulation of the principle of thermodynamic equilibrium, the law of conservation of energy, heat conversion, and zero temperature. However, in my opinion, one of the most important laws is the second law of thermodynamics, which can be stated in different ways.
Justification Based on Daily Activities
On the one hand, the entropy of an isolated system always tends to increase, which means that the measure of the disorder of such a system must increase. On the other hand, the law postulates the impossibility of converting heat into work without external changes. I would describe this law in simpler words: heat energy always passes from a more heated body to a less heated one, and never vice versa.
Applying Thermodynamics Concepts to Real-World Scenarios for Life Success
The second law of thermodynamics finds ubiquitous use in routine life outside of physics class. A hot water kettle continually cools down by giving up its heat to the surrounding air, as does a hot pizza or pie, an electric heater, melted wax, or any other object surrounded by a less warm environment. Another exciting thing is that if you put a hot, freshly cooked dish into a cold refrigerator, the second law of thermodynamics says that heat from the dish will be intensely transferred to the refrigerator. For this reason, the dish will cool down.
However, the refrigeration system will have to compensate for the extra heat, which can lead to failure; for this reason, it is best not to put hot food in the refrigerator. In general, this law describes the importance of the gradient in the transfer of energy: such a gradient can be observed in the passive movement of molecules, in the movement of crowds, and in any other medium where there is movement from something with a higher concentration to something with a lower concentration.
Ranking the Thermodynamics Laws: Insight and Reasoning
Speaking of all four laws of thermodynamics, I would rank them in the following order of decreasing vital importance: second law > first law > zero law > third law. The rationale for this order is simple: the second law has the most significant practical value; the first law says that energy goes nowhere, which also adds to the vital importance of this principle. The zero law is interesting regarding transitive relations and can be extrapolated to social relations and dynamic communications. Finally, the third law of thermodynamics talks about zero temperature and entropy minimization, which, however, seems irrelevant to real life to me.
