Thermoelastic properties of materials under high temperature using equation of state

Jeewan Chandra, Kuldeep Kholiya, Pooja K.Bhatt

The purpose of present study is to show first time the applicability of Singh and GuptaÂ’s integral form of equation of state not only for the Bulk materials but nanomaterials as well. This Equation is based on some mathematical technique and used to analyze the temperature dependence of thermal expansion coefficient, relative volume change and isothermal bulkmodulus. We are taking metals Ag and Au as bulk materials and fullerene (C60) as a nanomaterial. There is found an excellent agreement of our calculated values with the experimental data, which proves the validity of Singh and GuptaÂ’s equation of state for both bulk materials and nanomaterials on equal potential.
