Importance of Thermodynamics in Everyday Life

We are living in the century of technology and science where the introduction of science in our daily activities has transformed our lives. In this modern era, we are completely dependent on physics and we cannot deny this fact. 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. Hence, we can say that physics is a vital factor in our everyday life. Here we are going to discuss one of the most important topics in physics, i.e. Thermodynamics.

Thermodynamics is as old as the universe itself, and the universe is simply the largest known thermodynamic system. Mainly, it is all about energy i.e. how energy gets used and how it changes from one form to another. With thermodynamics, you can find out how efficient things are using energy for useful purposes, such as generating electricity, moving an airplane, or even riding a bicycle. The word thermodynamics has a Greek heritage. The first part thermo, conveys the idea that heat is somehow involved and the second part dynamics, makes you think of things that move.

Application of First Law of Thermodynamics in daily life:

  • Light bulbs transform electrical energy into light energy (radiant energy).
  • One pool ball hits another, transferring kinetic energy and making the second ball move.
  • Plants convert the energy of sunlight into chemical energy stored in organic molecules.
  • You are transforming chemical energy from your last snack into kinetic energy as you walk, breathe, and move your finger to scroll up and down this page.

Application of Second Law of Thermodynamics in daily life:

  • Jet engines
  • Spark-ignition engines
  • Fossil-fueled steam power plants
  • All the refrigerators
  • Deep freezers
  • Industrial refrigeration systems
  • All types of air-conditioning systems
  • Heat pumps

Application of Third Law of Thermodynamics in daily life:

  • The direct use of the Third Law of Thermodynamics occurs in ultra-low temperature chemistry and physics.
  • The applications of this law have been used to predict the behavior of different materials to temperature changes. 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.

We can conclude that thermodynamics is an important part of our daily life. The second law of thermodynamics plays the most important role in making our life easier, i.e. heat transfer, which relates to transfer of heat between two mediums. There are three modes of heat transfer: conduction, convection and radiation. The concept of heat transfer is used in wide range of devices like heat exchangers, evaporators, condensers, radiators, coolers, heaters, etc. These are some of the most important objects we use in our day to day life.
