Transformation réversible  : constamment en équilibre thermodynamique :
  P1=...=Pn
  T1=T2=...=Tn
Inégalité de Clausius :
  Somme Qi/Ti < 0
H= u + pV
  = Wu + Q ( a pression constante)
ΔH=Q + Wu ( a pression constante) = CpΔT
ΔU=W + Q = CvΔT
Adiabatique :
  ΔQ = 0
δW=-pdV
ΔS = Scrée + S échangée
dS = δQ/T + δS
Sc > 0 irréversible 
Sc = 0 si réversible
Pompe à chaleur :
  ec = Tc/Tc-Tf
Efficacite de Carnot :
  Ec = Tf/Tc-tf ( machine frigorique)
Adiabatique réversible :
  isentropique : 
    ΔS = 0
dS=1/T dH - V/T dp = 1/T dV + p/T dv
Coefficient thermo elastique :
  Xt = -1/v Drond V/Drond P à T constant
coefficient dilatation isobare :
  alpha = 1/v drond V/drond T à P constant
Pour un gaz parfait Cv = nR/gamma -1
Cp = nrgamma/gamma-1
Gamma = 5/3 pour un gaz monoatomique
Gamma =  7/5 pour diatomique
Loi de Laplace :
  T^G*P^1-Gamma = cst
  PV^gamma = cste
  TP^1-Gamma/Gamma = cste
Détente de Gay Lussac :
  ΔU = 0
isenthalpique :
  ΔH=0
isochore :
  ΔU = Q
monobare :
  ΔH=Q
Identité thermodynamique :
  dU=TdS - PdV
  dH=TdS + Vdp
Se = Int[t1;t2] δQ/T
