The relationship between the pressure and the corresponding change in volume provides an information regarding the compression of solids under the effect of pressure. The Murnaghan’s equation as well as the Birch equation need to be modified if we have to predict the pressure-volume relationship at elevated temperature. Such modification should be introduced in order to incorporate thermal effects.
In order to understand the thermodynamic behaviour of soluds adequately under the effect of high pressure and high temperature, we have to develop models for estimating the variations of thermal expansivity and bulk modulus [10]. The pressure dependence of thermal expansivity and temperature dependence of bulk modulus are directly related to each other and defined in terms of the Anderson-Gruneisen parameters [3, 4, 11]. It is, therefore of, central importance to investigate the variation of the Anderson Parameter under the effect of pressure and temperature [12-13]. The knowledge of the volume dependence of the Gruneisen parameter and the Debye temperature is also very useful for understanding the thermodynamic behaviour of solids [14-15]. in particular the volume dependence of the Gruneisen Parameter is required for investigating the equation of state [16] whereas the pressure dependence of Debye temperature is needed for studying the recoilless emission or absorption in the Mossbauer effect [17].
