These are some of the most important objects we use in our day to day life. For example, university students sometimes fail to recognize that heat and work are independent means of energy transfer. The body starts cooling down by transferring the body heat to the sweat. temperature) and b) application of the first law of thermodynamics to the adiabatic processes. 1 Applications of Thermodynamics Muhammad Umair Akram#1 Industrial & Manufacturing Engineering Department, NED University of Engineering and Technology University Road, Karachi-Sindh, Pakistan 1 im079um@gmail.com 2 umair.an@ymail.com I. One thing to keep in mind, heat is not lost but transferred attaining equilibrium with maximum entropy. But much more than this, the second law of thermodynamics was found to explain the working of steam engines. Again, this happens due to the first and second law of thermodynamics in action. The original Carnot cycle corresponds to the heat engines in which work is produced. The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes, distinguishing two kinds of transfer of energy, as heat and as thermodynamic work, and relating them to a function of a body's state, called Internal energy.. When explaining processes entailing temperature variation, students tend to adopt the ideal-gas law. Thermodynamic Chapter 1 Fundamental Concepts Muhammad Surahman. Mainly, it is all about energy i.e. Consequently, the body temperature or in other words internal energy is maintained by the food we eat. Sweating in a crowded room: In a crowded room, everybody (every person) starts sweating. The Zeroth Law Of Thermodynamics is one of the most important physical laws of thermodynamics which states that if two thermodynamic systems are in thermal equilibrium with the third thermodynamic system, then they all are in thermal equilibrium with each other. Thermodynamics is as old as the universe itself, and the universe is simply the largest known thermodynamic system. It will cool down. The laws of thermodynamics dictate energy behavior, for example, how and why heat, which is a form of energy, transfers between different objects. Physics helps us in several things like maintaining our health, transporting people and goods,  providing energy, constructing buildings, helping us communicate, stimulating the economy and much more. Application of First Law of Thermodynamics in daily life: Light bulbs transform electrical energy into light energy (radiant energy). The word thermodynamics has a Greek heritage. When discussing adiabatic processes for an ideal gas, few students can correctly refer to the concept of "work" to justify a change in temperature. Light bulbs transform electrical energy into light energy (radiant energy). Explain the role of latent heat while phases are changing. 0 = ΔQ – ΔW. In this example, a zeroth law of thermodynamics plays an important role.. Don’t worry, I’ll explain to you everything about it. ΔU =Q – W. to an organism of the human body. In a shivering winter season, if your mom prepares a nice hot coffee for you and you do not drink it within few minutes, then what happens? Sweat evaporates adding heat to the room. This statement defines the zeroth law of thermodynamics. The law is based on temperature measurement. Charles Law application in real life can be seen in our kitchen too. The literature has revealed that many students encounter substantial difficulties in applying the first law of thermodynamics. 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. Group 3 EKC222 Chemical Eng. The idea of a machine with 100% thermal efficiency is rejected. ; Thermodynamics is the study of the relationship between heat, temperature, work, and energy.

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. The concept of heat transfer is used in wide range of devices like heat exchangers, evaporators, condensers, radiators, coolers, heaters, etc. One pool ball hits another, transferring kinetic energy and making the second ball move. The first law of thermodynamicswould not be violated if any of these processes occurred in reverse. Details of when, how, and why each example is adopted, along with the students' pitfalls, are described below. ΔW = ΔQ. Whenever heat (Q) is added to the system, the change in total energy of the system (∆E) increases. From the above statement, the first law of thermodynamics states that when a system undergoes a thermodynamic cycle then the net heat supplied to the system from its surroundings is proportional to the network done by the system on its surroundings.
