Temperature dependence of volume expansion for solids

In the present communication, an empirical relationship for temperature dependence of volume expansion is reported at atmosphere pressure for solids. The solids MgO, CaO, Al2O3 and Mg2SiO4 are considered for the study. The newly developed relationship is based on the studies done by Srivastava and Singh and Chauhan on the basis of the fact that isothermal bulk modulus decreases linearly with temperature. A close agreement between the theory and the experiment reveals the validity of the present work.
