**Euler relations** =================== *Euler relations* are thermodynamic equations relating thermodynamic potentials with parameters of the system such as pressure, volume, temperature, entropy, etc. They are also called *Euler integrals* because they feature not differentials of thermodynamic potentials, but their integrated forms. They are derived using `Euler's homogeneous function theorem `_. .. py:currentmodule:: symplyphysics.laws.thermodynamics.euler_relations **Contents:** .. toctree:: :maxdepth: 4 laws.thermodynamics.euler_relations.enthalpy_formula laws.thermodynamics.euler_relations.gibbs_energy_formula laws.thermodynamics.euler_relations.internal_energy_formula
