Graphical summaries for Maxwell relations of closed and open thermodynamic sy…

An attempt has been made to ‘condense’ the thermodynamic relations of equilibrium thermodynamics by using graphics. Two simple mnemonic models named as ‘Thermodynamic Circle-1’and ‘Thermodynamic Circle-2’ are reported to represent the Maxwell relations geometrically so that these relations for both closed and open thermodynamic systems can be easily recalled. Keywords thermodynam…
