| Abstract: | Starting from the second law of Gruneisen and making use of universal potential energy function as interaction potential function between atoms, we calculated thermal expansion coefficients of the cubic crystal metallic elements and alkali halide crystals at room temperature. The calculated value is in a very suitable agreement with the experimental value. |

| Keywords: | thermal expansion coefficient Universal potential energy function Cubic crystal metallic element Alkali halide crystal |
