Query: Equation of state for tungsten over a wide range of densities and
  internal energies   A caloric model, which describes the pressure--density--internal-energy
relationship in a broad region of condensed-phase states, is applied for
tungsten. As distinct from previously known caloric equations of state for this
material, a new form of the cold-compression curve at $T = 0$~K is used.
Thermodynamic characteristics along the cold curve and shock Hugoniots are
calculated for the metal and compared with some theoretical results and
experimental data available at high energy densities.
