Attribute definitions:

SpecificHeatCapacity | : | Defines the specific heat of the material: heat energy absorbed per temperature unit. Usually measured in [J/kg K].
BoilingPoint | : | The boiling point of the material (fluid). Usually measured in Kelvin.
FreezingPoint | : | The freezing point of the material (fluid). Usually measured in Kelvin.
ThermalConductivity | : | The rate at which thermal energy is transmitted through the material.Usually in [W/m K].
