It is an excellent textbook for undergraduate students who are studying in materials science. Each chapter contains a summary and nearly every chapter provides detailed examples. The new edition includes additional thermodynamic work terms beyond pdV or Tds or udN such as magnetic work and how the fields within these work terms are experimentally relevant. The thermodynamic consideration of magnetic materials is particularly useful for graduate students working on magnetic materials.
I find the effect of magnetism and magnetic work in the analysis very useful. Many examples are laid out in details, and numerous diagrams are given to make sure that a solid understanding is reached. Therefore, this book gives solid foundations in thermodynamics for engineering students. Equipped with this knowledge, the students can go on toward more specialized studies or to the reading of research papers.
It would be ideal for undergraduate students who are learning this topic for the first time, but is also useful as a refresher of the fundamentals for graduate students and researchers working in this field. The inclusion of worked examples and problems is particularly valuable in helping to practice the application of thermodynamic theory to real examples in Materials Science.
This book can easily bring them to enter the world of Thermodynamics of Materials and make them well know concept about Thermodynamics. I believe the emphasis on graphical representations of thermodynamic data is a very real strength for interpreting this material to the beginner. I also see significant improvements in the organization that provides greater clarity. The addition of qualitative example problems at the end of each chapter is welcome.
The new Chapter 15 is a valuable contribution. This chapter is probably unlikely to be used in undergraduate teaching, but it will be extremely useful for a new generation of graduate students.
Gaskell and David E. Laughlin, is the need of the hour. Although Professor Gaskell is not among us physically to inspire us, his legacy will be seen whenever we open this book on thermodynamics of materials. A great effort from Professor Laughlin in bringing out this revised edition. Rajulapati, University of Hyderabad, India. It is very clear in explaining the complex meaning of the thermodynamics rules and equations, starting from the potentials and their use to solve thermodynamics problems.
Without being too advanced, it reaches all the necessary points for a thorough discussion of the matter, even entering in some detail which is not often taught in the undergraduate courses, I really appreciate the clarity and the accuracy of the language.

Marc De Graef. Structure and Bonding in Crystalline Materials. Gregory S. Editorial Reviews Review "I love this book and will strongly recommend it to my students. Rajulapati, University of Hyderabad, India "This textbook has a very rigorous and deep approach to chemical thermodynamics. Product details File Size: Up to 4 simultaneous devices, per publisher limits Publisher: August 15, Sold by: English ASIN: It would be equally acceptable to define V and T as the independent variables and define the system by an equation of state for pressure: Other systems require more variables, but the number required is always relatively small.
The volume of the system will depend not only on P and T, but also on which gases are present. As above, this new equation of state could be done instead as an equation for P in terms of V, T, and composition: Pressure or volume are all that are needed to define mechanical stimuli on a gas or a liquid. For solids, however, the matter might experience various states of stress and strain.
For a pure solid, the natural variables are temperature, stress s instead of P , and strain e instead of V. Unlike P and V which are scalar quantities, stress and strain are tensors with 6 independent coordinates.
If the material is not a pure material, such as a composite material, the stress-strain relations will also depend on the compositions of the material and typically on the geometry of the structure. For interactions of matter with other stimuli suich as electric or magnetic fields, the equations of state will also depend on the intensity of those fields.
Thus, in summary, the thermodynamic state can also be expressed as an equation of state that is a function of a relatively small number of variables. The simplest examples involve only two variables. More complicated systems require more variables. Thus equations of state follow the rules of mutlivariable mathematics. In thermodynamics, we are often concered with how something changes as we change the independent variables.
A general analysis of such a problem can be written down purely in mathematical terms. This Mathematica notation will be used throughout these notes which were prepared in a Mathematica notebook. Many input expressions are followed be semicolons which simple supresses uninteresting Mathematica output. Any change in volume due to a change in T and P can be calculated by integrating dV: In thermodynamics we are usually dealing with physical quantities. In general, the partial derviatives for the total differentials themselves often have physical significance.
In other words, they often correspond to measurable quanties. Sometimes the physical significance is not clear. In such problems, the partial derivative is defined as having having physical significance or it becomes a new thermodynamic quantity. One good example to be encountered later in this course is chemical potential. For example V is a state variable. It depends only on the independent variables P, T, and perhaps others and not on the path taken to get to the variables.
There are many thermodynamic state variables and they are very important in thermodynamics. There are some thermodynamic quantities that are not state variables. The two most important are heat and work. The heat supplied to a system or the work done by a system depend on the path taken between states and thus by definition, heat and work are not state variables. The previous sections define equations of state for matter.
Equilibrium is the state of the system when the variable reaches the value it should have as defined by the equation of state. For example, a pure gas has an equation of state V[P,T]. Equilibrium is reached when after changing P and T to some new values, the volume becomes equal to the V[P,T] defined by the equation of state.
All systems naturally proceed towards equilibrium. They are driven there by natural tendencies to minimize energy and to maximize entropy. These concepts will be discussed later.
Although all systems tend towards equilibrium, thermodynamics says nothing about the rate at which they will reach equilibrium. Some systems, particularly condensed solids as encountered in material science, may not approach equilibrium on a pratical time scale. Boyle found that at constant T that V is inversely proportional to P.
These are the units of work or energy. When R was first measured, P was measured in atm and V in liters; thus P V or work or energy has units liter-atm. SI units for energy is Joules. The first law of thermodynamics connects the two energy units and allows one to relate heat and work energy or to relate calories and Joules. Extensive variables depend on the size of the system such as volume or mass.
Intensive variables do not depend on the size such as pressure and temperature. Extensive variables can be changed into intensive variables by dividing them by the mass or number of moles. Such intensive variables are often called specific or molar quantities. For example, the volume per mole or molar volume is an intensive variable of a system.
Similarly, mass is an extensive property, by mass per unit volume or density is an intensive property. Systems are characterized by the number of components and the type of phase diagrams depend on the number of components. Examples are one-component unary , two-component binary , three-component ternary , four- component quarternary , etc.. In each zone, one state is the most stable state. On lines, two phases can coexist. At triple points, three phases can coexist. Example of unary is water phase diagram.
Unary diagrams usually use two variables like P and T. Binary diagrams add composition as a third variable. Binary diagrams are usually for one variable T, P, or V together with the composition variable.
The complete phase space is 3D. Thus, 2D binary plots are sections of the 3D curves. Zones can be single phase solutions or two-phase regions. The relative proportions of phases in two- phase regions are given by the lever rule. Choice of components is arbitrary.
First law connected heat and work and clarified conservation of energy in all systems. The key new energy term that developed from the first law is internal energy.
Internal energy often has a nice physical significance; sometimes, it significance is less apparant. The first law says energy is conserved, but it makes no statement about the possible values of heat and work. The second law defines limits on heat and work in processes. It was used to define the efficiency of heat engines. The second law also lead to the definition of entropy. Entropy was slow to be accepted, because it has less apparant physical significance than internal energy.
Rougly speaking, entropy is the degree of mixed-upedness. Some thermodynamic problems require an absolute value of entropy, the third law of thermodynamics defines the entropy of a pure substance at absolute zero to be zero. The principles of thermodynamics is are nearly fully defined after defining the laws of thermodynamics, internal energy, and entropy.
The rest of the study of thermodynamics is application of those principles to various problems. All systems try to minimize energy and maximize entropy. Most problems we ever encounter can be solved from these basic principles. It turns out, however, that direct use of internal energy and entropy can be difficult. Instead, we define new functions called free energy - Gibbs free energy or Helmholz free energy.
These new energies perform the same function as other thermodynamics functions, but that are physcially much more relevant to typical problems of chemistry and material science. In particular, Gibbs free energy is the most common term needed for chemical and material science problems that are typically encounted in various states of applied temperature and pressure. Chapter 2: The total change in internal energy is thuys always given by: The total change in enthalpy can be written two ways as: The values for heat and work during a change of state, however, will depend on path.
This section gives some results for heat and work during some common processes: Heat and work are thus: Any Processes For any other process, w can be calculated for the P dV integral and q from the first law of thermodynamics.
This result applies for both reversible and irreversible processes; P, however, will be given by an equation of state only for reversible processes.
Here are some constants defined in a table used to get numerical results: All results are given in Joules: DU for isothermal step is zero because of the ideal gas.
The constant volume step is same as above and thus obviously gives the same result. This extra work is not needed because in all cases, DU can be calculated directly from the same information used to first get DH.
Finally, adiabatic compression to 1 atm returns to initial volume. Isobaric compression to 25C returns the gas to its initial state state 1 above. After returning to the intial state, the total work comes from the isobaric steps only; the constant volume steps do no work. Simpler expressions hold in some special cases. From the general equation above, DS is also obviously zero because PVg is constant during a reversible adiabatic processes.
There are two results for each term; either can be used, depending on which one is easier: For free expansion of ideal gas, temperature remains constant. Here the volume triples. For any isothermal expansion to triple the volume, the state functions results are the same as part a.
But here the process is reversible. At constant pressure q is equal to DH and work follows from that results: Heat flow is an integral of the constant-pressure heat capacity. If the heat capacity is independent of temperature, the final temperature will be the average of the two initial temperature. The engine operates in a cycle and thus must have no entropy change. Chapter 4: Chamber 1 has 1 mole of A and chamber 2 has 1 mole of B. These ideal gases do not interact and thus the total energy change is the sum of entropy changes for each type of gas: When there are 2 moles of A in chamber 1, the entropy change for that gas doubles giving: Notes on Gaskell Text 33 c.
When each chamber has gas A, we can not use the methods in parts a and b because they no longer act independently.
When each chamber has 1 mole of A, removing the partition does not change anything. When one chamber has 2 moles of A and the other has 1 mole of A, the two chambers will be at different pressures and removing the partition will causes changes and a non-zero change in entropy.
This problem is best solved by first moving the partition to equalize pressures. Thus the total change in entopy can be calculated from the initial change in volumes done to equalize pressures: Chapter 6: This answer can be obtained by using 0. The Handbook of Chemistry and Physics gives the thermal expansion of Copper as as 0. Thus the text gave the wrong value in the problem, but used the correct value to derive the solution.
Using the correct thermal expansion changes the above results to: This method works because total enthalpy is conserved for adiabatic, constant pressure conditions. For the reaction in air starting with one total mole of reactants, the fractions are. The DGsimp agrees with the book, but the DG in the book is different. Some books have 9 problems that correctly correspond to the 9 solutions. Other books probably early printings of the thrid edition are missing the problem that goes with the first solution and have an extra problem that has no solution.
These notes give the solutions to the 8 problems in common to all books. Some books have them as 7. Once the vapor-liquid equilibrium is reached at constant volume, the P and T will remain on the transition curve but the vapor pressure will change with temperature. Also, Table A-4 gives the second equation as the vapor pressure curve for liquid Zn. The leading constant of Thus under atmospheric conditions, solid CO2 vaporizes into gaseous CO2. You are also given the slopes of the lines emanating from the triple point by using the Clapeyron equation: This problem is solved in the text see page Mixing of ideal gases is puring due to entropy effects.
The maximum increase in entropy occurs when there are equal parts of each gas. From partial molar results eq. If you pay by the mole, you would prefer the ideal gas because it would be cheaper. If you pay by the container, you would prefer the van der Waals gas because you would get more moles per dollar. Pressure is given by the virial expansion, so all we need are the initial and final volumes. To find work done by the gas, we integrate P from V1 to V2 or to find the work done on the gas we reverse the integration and go from V2 to V1.
The result after convertion to joules is. Positive work must be done on a system to compress it. Finally, the ideal gas result can come for either above result by setting extra constants to zero, or by directly integrating the ideal gas result:
