Basic thermodynamics is fundamentals topic in thermal engineering. The subject deals with the study/behaviour of thermodynamic system and its equilibrium based on laws of thermodynamics and to understand various forms of energy – heat transfer and work. Evaluating the feasibility of cyclic and non-cyclic processes using the laws of thermodynamics. Definition of entropy, reversibility and irreversibility, closed and open thermodynamic systems. Determine the quantity of energy transfers and change in properties to study the behaviour of pure substances and its application in industrial problems. Recognize the differences between ideal and real gases and evaluate thermodynamic properties of ideal and real gas mixtures using various relations derived from the laws of thermodynamics.
