Perpetual Motion Machine of Second Kind
Perpetual motion machines are defined as devices that work while connecting with only one heat reservoir. These devices are considered to violate the second law of thermodynamics. These machines do not exist in the real life and only exist theoretically.
We know that a heat engine interacts with two heat reservoirs at different temperatures to produce work in a cycle. Differences in the temperature of the two reservoirs result in the work being produced until the temperature in both reservoirs is equalized.

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.
