Knowledge in partial diferential equations theory and thermodynamicsThe main thermodynamical variables are energy E , enthalpy H , free energy of Helmholtz A , free energy of Gibbs G, entropy S , temperature T , pressure P , and volume V .It is possible to form 336 partial derivatives of the type(∂X/∂Y)S , where X ,Y ,Z and are among these eight variables.The Jacobian notation shows thermodynamic derivatives in an elegant mannerComponente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
