WebEngineering Thermodynamics: A Graphical Approach An enthalpy–entropy chart, also known as the H–S chart or Mollier diagram, plots the total heat against entropy, describing the enthalpy of a thermodynamic system. A typical chart covers a pressure range of 0.01–1000 bar, and temperatures up to 800 degrees Celsius. It shows enthalpy See more The diagram was created in 1904, when Richard Mollier plotted the total heat H against entropy S. At the 1923 Thermodynamics Conference held in Los Angeles it was decided to name, in his honor, … See more It can be used in practical applications such as malting, to represent the grain–air–moisture system.
