2.1 Introduction

We learnt about system and processes in Chapter 1. The questions that come to our mind are (i) whether or not the system can execute the given process, (ii) if yes, then what type and how much interaction is taking place between the system and the surrounding, and lastly, (iii) what effects are left on the system and the surrounding after completion of the process. The questions are answered by thermal analysis of the system, which is based on the ...
