PREMIER PRINCIPE:
  deltaU= m x c x(Tf-Ti)
  deltaU= m x c x deltaT
  C= m x c
  m= ro x V
  deltaU= W x Q

    deltaU en J
    deltaT en K ou Co
    m en kg
    c en J.kg^-1.K^-1
    C en J.K^-1
_______________________________
LA CONDUCTION:
  fi= Q/ delta t
  Rth= T1-T2/ fi
  Rth= e/ lambda x S
  
    e en m
    S en m^2
    lambda en W.m^-1.K^-1
    Rth en K.W^-1
    fi en W
    T en K ou Co
    delta t en s
    Q en J
______________________________
LA CONVECTION:
  fi= h x S x(Tth-T(t))
  T(t)= (T0-Tth).e^-kt +Tth
  
    fi en W
    T en K ou Co
    S en m^2
    h en W.K^-1.m^-2

LE RAYONNEMENT:
  P= sigma x T^4
  
    P en W.m^-2
