High temperature results use the room-temperature 3rd-order Birch-Murnaghan equation of state
in which the room temperature parameters K0 and K'0 are replaced by their high-temperature counterparts:
KT and K'T and V0 is replaced by VT.
We call this the high-temperature Birch-Murnaghan equation of state.
