Accounting for the Violation of Adiabatic Conditions in Measurements of the Adiabatic Thermal Coefficient of the Pressure of Conducting Liquids

An analytical formula for an adjustment function, taking the violation of adiabatic conditions in the dynamic measurements of the adiabatic thermal pressure coefficient for conducting liquids [1] into account, has been obtained. The formula is corroborated by numerical calculation. It has been shown that the correction can be on the order of 1 to 7%, depending on the electroconductivity of the material and geometry of the experiment. The determination of the adjustment function is of great importance in the study of structural transitions in metallic liquids.
