Correlation of temperature dependencies of the thermal expansion and heat capacity of refractory metal up to the melting point: Molybdenum
Annotation
By the example of molybdenum, the detailed correlation investigation between the volume thermal expansion coefficient, $\text{o}(T)$, and the heat capacity, $C(T)$, of the refractory metal is carried out. It is shown that distinct correlation of $\text{o}(C)$ takes place not only within the low temperature region where it is linear and is known as the Gr?neisen law but also within a much wider temperature region, up to the melting point of the metal. Sufficient deviation of the $\text{o}(C)$ dependency from the low temperature linear behavior takes place when the heat capacity achieves its classical Dulong and Petit limit, $3R$.
