thermodynamique : science de l'énergie
description macroscopique du système ( thermo classique)
mecanique statique et thermo statique ( échelle micro et méso)
Volume spécifique = 1 / ro 
transfo quasi statique : à chaque instant très proche de l'équilibre
Transfo réversible : système passe par une suite d'état d'équilibre
Transfo irréversible : système qui ne remplissent pas les conditions
1 kWh = 3600 kJ
1 tonne de pétrole = 11630 kWh
1 ev 1.6 *10^-19 J
la calorie = 4.18 J
1 Btu = 1050 J
1 logement = 16 500 kWh/an
Delta U = W + Q
PV = nRuT
diagramme de transformation PV
transfo isobare : 
  W = - P0 Delta V
Transfo isother =me :
  W = -nRu T0 ln (Vf/V0)
  Adiabatique réversible : 
    P(V)gamma = constante, T(V)gamma-1 = constante
pente adiabatique > pente isotherme
Ru = 8.314
