The laws of thermodynamics dictate energy behavior, for example, how and why heat, which is a form of energy, transfers between different objects. When a body ‘A’ is in thermal equilibrium with another body ‘b’, and also separately in thermal equilibrium with a body ‘C’, then body ‘B’ and ‘C’ will also be in thermal equilibrium with each other. By the first law of thermodynamics, ΔU = q + W. ∴ 0 = q + W. ∴ q = -W or W = – q. Thermodynamics Melchor Potestas. One thing to keep in mind, heat is not lost but transferred attaining equilibrium with maximum entropy. Details of when, how, and why each example is adopted, along with the students' pitfalls, are described below. Recommended, Top 6 Real-Life Applications of Boyle’s Law. The concept of reversibility, Carnot cycle and Carnot principle is introduced. In order to help students comprehend the meaning, usages, and value of the first law, and to realize that the ideal-gas law itself is insufficient to analyze many real-life examples, this paper introduces four examples, some of which can be demonstrated in the classroom. Consequently, the body temperature or in other words internal energy is maintained by the food we eat. ; Thermodynamics is the study of the relationship between heat, temperature, work, and energy. It was seen that most of the teacher candidates experienced difficulty in understanding the fact that there was no difference between the functions of the concepts of heat and work in the microscopic scale. This law explains how you heat the water and make hot coffee, why the hot coffee in your mug gets cooled etc. Whether you are travelling in any vehicle, sitting comfortably in your air-conditioned room, watching television etc, you will notice the applications of thermodynamics almost everywhere directly or indirectly. The zeroth law of thermodynamics is one of the four laws of thermodynamics, which states that if two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with one another. 0 = ΔQ – ΔW. The first law of thermodynamicswould not be violated if any of these processes occurred in reverse. These relationships have become core to many scientific disciplines, although the Third Law of Thermodynamics is not directly utilized as much as the other two. Application of First law of thermodynamics. Again, this happens due to the first and second law of thermodynamics in action.
