ENGINEERING THERMODYNAMICS What is Thermodynamics?  Thermodynamics is a science dealing with Energy and its transformation and its effect on the physical properties of substances.  It deals with equilibrium and feasibility of a process.  Deals with the relationship between heat and equilibrium. work and the properties of systems in Scope of Thermodynamics:  Steam power plant  Separation and Liquification Plant  Refrigeration  Air-conditioning and Heating Devices.  Internal combustion engine  Chemical power plants  Turbines  Compressors, etc The principles of thermodynamics are summarized in the form of four thermodynamic laws:

The Zeroth Law deals with thermal equilibrium and provides a means for measuring temperatures. The First Law deals with the conservation of energy and introduces the concept of internal energy. The Second Law of thermodynamics provides with the guidelines on the conversion of internal energy of matter into work. It also introduces the concept of entropy. The Third Law of thermodynamics defines the absolute zero of entropy. The entropy of a pure crystalline substance at absolute zero temperature is zero. Different Approaches of Thermodynamics : Write the difference between Macroscopic and Microscopic approach of Thermodynamics: Macroscopic Approach Microscopic Approach 1.Macroscopic approach is known as Classical Thermodynamics. 1. Microscopic approach Statistical Thermodynamics is known 2. Attention is focussed on a certain quantity of 2. A knowledge of the structure of matter matter without taking into account the events under consideration is essential. occuring at molecular level. as
