Thermodynamics Of Materials Pdfkeyclever

Posted By admin On 21.04.21

Thermodynamics is the branch of science concerned with heat and temperature and their relation to energy and work. Being concentrated on a wide range of applications of thermodynamics, this book gathers a series of contributions by the finest scientists in the world, gathered in an orderly manner. The thermodynamic properties of materials are intensive thermodynamic parameters which are specific to a given material. Each is directly related to a second order differential of a thermodynamic potential. Examples for a simple 1-component system are.

The thermodynamic properties of materials are intensive thermodynamic parameters which are specific to a given material. Each is directly related to a second order differential of a thermodynamic potential. Examples for a simple 1-component system are:

Compressibility (or its inverse, the bulk modulus)

Isothermal compressibility

{displaystyle beta _{T}=-{frac {1}{V}}left({frac {partial V}{partial P}}right)_{T}quad =-{frac {1}{V}},{frac {partial ^{2}G}{partial P^{2}}}}

Adiabatic compressibility

{displaystyle beta _{S}=-{frac {1}{V}}left({frac {partial V}{partial P}}right)_{S}quad =-{frac {1}{V}},{frac {partial ^{2}H}{partial P^{2}}}}

Specific heat (Note - the extensive analog is the heat capacity)

Specific heat at constant pressure

{displaystyle c_{P}={frac {T}{N}}left({frac {partial S}{partial T}}right)_{P}quad =-{frac {T}{N}},{frac {partial ^{2}G}{partial T^{2}}}}

Specific heat at constant volume

{displaystyle c_{V}={frac {T}{N}}left({frac {partial S}{partial T}}right)_{V}quad =-{frac {T}{N}},{frac {partial ^{2}A}{partial T^{2}}}}

Coefficient of thermal expansion

{displaystyle alpha ={frac {1}{V}}left({frac {partial V}{partial T}}right)_{P}quad ={frac {1}{V}},{frac {partial ^{2}G}{partial Ppartial T}}}

where P is pressure, V is volume, T is temperature, S is entropy, and N is the number of particles.

For a single component system, only three second derivatives are needed in order to derive all others, and so only three material properties are needed to derive all others. For a single component system, the 'standard' three parameters are the isothermal compressibility ${displaystyle beta _{T}}$ , the specific heat at constant pressure ${displaystyle c_{P}}$ , and the coefficient of thermal expansion ${displaystyle alpha }$ .

For example, the following equations are true:

{displaystyle c_{P}=c_{V}+{frac {TValpha ^{2}}{Nbeta _{T}}}}

{displaystyle beta _{T}=beta _{S}+{frac {TValpha ^{2}}{Nc_{P}}}}

The three 'standard' properties are in fact the three possible second derivatives of the Gibbs free energy with respect to temperature and pressure.
