摘要: Abstract An experimental equation of state for sodium has been obtained pressures to 20,000 atm and temperatures from 20°K the melting point. Various details are given an apparatus with which it is possible obtain pressure-volume data reliable ± 0002 in ΔV V 0 over this range temperature pressure. The can be represented within above accuracy by expression derived assumption that isothermal compressibility linear volume no explicit dependence. A discussion effect these assumptions on validity calculations variation dependent contribution thermodynamic functions. Grueneisen onstants as various definitions calculated functions volume, Mie-Grueneisen applies appears open question below room temperature. Recent high pressure ultrasonic experiments interpreted being agreement conclusion.
