Extreme compression behaviour of equations of state

J Shanker, P Dulari, PK Singh - Physica B: Condensed Matter, 2009 - Elsevier
The extreme compression (P→∞) behaviour of various equations of state with K′∞> 0
yields (P/K)∞= 1/K′∞, an algebraic identity found by Stacey. Here P is the pressure, K the …
