Second Law of Thermodynamics: Applications in Real Life

Here are the Applications and Uses of Second Law of Thermodynamics:

  • The law states that heat always moves from a body that is warmer to a body that is colder. All heat engine cycles, including Otto, Diesel, etc., as well as all working fluids employed in the engines, are covered by this rule. Modern automobiles have advanced as a result of this law.
  • Refrigerators and heat pumps that use the Reversed Carnot Cycle are other examples of how this concept is applied. You must provide external work if you want to transfer heat from a body with a lower temperature to a body with a greater temperature. Unlike the Reversed Carnot Cycle, which uses work to move heat from a lower-temperature reservoir to a higher-temperature reservoir, the original Carnot Cycle uses heat to produce work.

Second Law of Thermodynamics

Second Law of Thermodynamics defines that heat cannot move from a reservoir of lower temperature to a reservoir of higher temperature in a cyclic process. The second law of thermodynamics deals with transferring heat naturally from a hotter body to a colder body.

Second Law of Thermodynamics is one of three Laws of Thermodynamics. The word “thermodynamics” comes from two root words: “thermo,” meaning heat, and “dynamic,” meaning power.

This article explores the second law of thermodynamics, along with its different statements, equations for the second law, examples, and applications in real life.

Conclusion of Second Law of Thermodynamics

Second Law of Thermodynamics states that heat naturally flows from a hotter body to a cooler one and cannot move in the opposite direction without external energy. This law introduces the concept of entropy, meaning the disorder in an isolated system always increases over time. It explains why refrigerators need power to work and why perfect energy efficiency is impossible. Second Law has important applications in designing engines and predicting the universe’s energy balance....
