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].
