Thermodynamics deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics. The science of thermodynamics is a very sweet and conceptual science. Many concepts that we face in reality are examined in thermodynamics. Laws of thermodynamics, entropy generation and analysis and investigation of various thermodynamic cycles, etc. are things that are taught in class. references : Cengel , Borgnakke.
