coeff de dilatation a P cste
alpha=1/V(dV/dT)P
=1/T

coeff daugmentation de P a V cst
beta=1/P(dP/dT)V
=1/T

coeff de compressibilite isotherme
Xt=-1/V(dV/dP)T
=1/P

(dV/dP)T(dV/dT)P(dT/dP)V=-1
(dV/dT)P(dT/dP)V=-(dV/dP)T
1/V(dV/dT)P(dT/dP)V=-1/V(dV/dP)T
alpha (dT/dP)V = xT
alpha = xT (dP/dT)V
1/P alpha = xt 1/P(dP/dT)V
alpha = xT beta P
