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:

K_T and K'_T and V₀ is replaced by V_T.

We call this the high-temperature Birch-Murnaghan equation of state.
