  From experimental observations of limiting temperatures in heavy ion
collisions we derive Tc, the critical temperature of infinite nuclear matter.
The critical temperature is 16.6 +- 0.86 MeV. Theoretical model correlations
between Tc, the compressibility modulus, K the effective mass, $m^*$ and the
saturation density, rho_s, are exploited to derive the quantity
(K/m^*)**1/2*rho_s^{-1/3}$. This quantity together with calculations employing
Skyrme and Gogny interactions indicates a nuclear matter incompressibility in
moderately excited nuclei that is in excellent agreement with the value
determined from Giant Monopole Resonance data. This technique of extraction of
K may prove particularly useful in investigations of very neutron rich systems
using radioactive beams.
