Thermodynamics is an essential subject in the study of the behaviour of gases and vapours in real
This book is a complimentary follow up for the book “Engineering Thermodynamics” also published on
BOOKBOON, presenting the solutions to tutorial problems, to help students to check if their solutions
are correct; and if not, to show how they went wrong, and change it to get the correct answers.
Thermodynamics is an essential subject taught to all science and engineering students. If the coverage of this subject is restricted to theoretical analysis, student will resort to memorising the facts in order to pass the examination. Therefore, this book is set out with the aim to present this subject from an angle of demonstration of how these laws are used in practical situation.This book is designed for the virtual reader in mind, it is concise and easy to read, yet it presents all the basic laws of thermodynamics in a simplistic and straightforward manner....
Chapter 2 - Energy, energy transfer, and general energy analysis. In this chapter, we consider each of these modes of energy transport across the boundaries of the general thermodynamic system. Learning objectives of this chapter include: Introduce the concept of energy and define its various forms, define the nature of internal energy, define the concept of heat and the terminology associated with energy transfer by heat.
Chapter 4 - Energy analysis of closed systems. After studying this chapter you will be able to: Identify the first law of thermodynamics as simply a statement of the conservation of energy principle for closed (fixed mass) systems, identify the types of energy that may be transferred to or from a closed (fixed mass) thermodynamic system, develop a step-by-step intuitive approach to the application of the conservation of energy principle,...
We knew that the concepts of mechanical work and energy play an
important role in studying mechanical phenomena.
Concerning to thermal phenomena, there exits a new form of energy
Heat can be transferred from one to other systems
For a system with volume held constant, the effect of heat is to
change the temparature of a system.
The first law of thermodynamics gives the quantiative relations between
the internal energy of a system and the quantities of heat and work that
the system exchange with surroundings. It express the conservation of
The first law of thermodynamics is true, but not enough ! Why ?
Many thermodynamic processes which don’t violate the 1st
but don’t happen in nature !
