It was period of my undergraduate study at Mumbai University‚ during which I developed an acumen towards chemistry and chemical science. The orientation before practical session increases my eagerness about chemistry to the zenith of my learning. At that moment I decided to pursue my career in chemistry and grab every opportunity where I can enhance my learning of the subject and deepen my conceptual knowledge of the subject. The sole reason for this alacrity‚ I would attribute to my undergraduate

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the
