Every science has an idiosyncratic vocabulary associated with it, and thermodynamics is no exception. In everyday life, everything uses energy, but does that mean the energy is lost? Of that energy that is being used, what is the quality of that energy and is it increasing or decreasing? Through thermodynamics, these types of question can be solved using the different laws. Thermodynamics can be defined as the science of energy. The name thermodynamics is derived from the Greek words therme, meaning heat and dynamis, meaning power. Thermodynamics is at work in our everyday lives, yet most people have no idea it 's there. In order for a system to gain energy the surroundings have to supply it, and when the system loses energy the surroundings must gain it. The first law of thermodynamics states that energy can neither be created nor destroyed during a process, but energy can only be transformed from one form to another. Energy exists in two forms: potential energy which is stored energy available to do work, and kinetic energy which is the energy used to do work. According to the first law of thermodynamics, the total amount of energy in the universe is constant. Several examples of the applications of the first law of thermodynamics include: Energy from the sun, Metabolism of the human body, Burning wood, Steam Engines, Refrigerators.
The sun is the main source of energy for living organisms. Some living organisms like plants require direct sunlight while some other…
