Basic Thermodynamics Prof. S. K. Som Department of Mechanical Engineering Indian Institute of Technology, Kharagpur Lecture – 01 Introduction and Fundamental Concepts Good morning to all of you in this session of thermodynamics. I welcome you all to this session. Now first I will describe you, what the subject thermodynamics is? What its contents is, which is very important to know before going to learn this subject. Now the word thermodynamics originates from the word therme, it is a Greek word. We can write this therme. (Refer Slide Time: 01:40)
Therme is a Greek word which means heat and dynamic which is force. The word thermodynamics originates from these two words. This is the classical history of thermodynamics. Little bit you should know these things. In primitive days understanding of thermodynamics centered around the concept of getting power from hot bodies or getting power from heat, abilities of hot body to produce work, which is partly the scope of mechanical engineering thermodynamic student but the scope of thermodynamics is much wider or much
