Important Notes

Vapor Pressure & Boiling Point: The boiling point of a liquid metal is dependent on the ambient pressure. Data is provided at two standard reference pressures: 10⁻³ atm and 10⁻⁶ atm.
Specific Heat: This is the amount of heat energy required to raise the temperature of a unit mass of the liquid metal by one degree Celsius (or Kelvin).
Unit Conversion: The specific heat is given in both calorie and SI units. 1 cal/g·°C = 4.1868 kJ/kg·°C.

For reference, 1 atm = 101325 Pa = 1.013 bar = 14.696 psi = 760 torr.
