Chapter 2

Work and Heat

LEARNING OBJECTIVES
  • To be able to differentiate between Thermodynamics and Mechanics definition of work
  • To evaluate work done in quasistatic processes
  • To identify and evaluate work in non-thermodynamic interactions
  • To know the difference between heat interaction and work interaction
  • To prove that work and heat are path functions
  • To know the sign convention for work and heat
  • To know the molecular basis of heat and work

2.1 Introduction

The first chapter defined terms and described elements that form the basis for thermodynamic analysis. In this chapter, we will consider two interactions central to the subject of thermodynamics, namely work and heat. Both these interactions are energy transfer processes. Work is a ...
