Module 3 :
Lecture 11 : Phase-Change Process of Pure Substances
 



Graphical Representation of Data for Pure Substances

 

The commonly used thermodynamic diagrams are

 

  1. Pressure versus Temperature ( P − T )

  2. Pressure versus Volume ( P − )

  3. Temperature versus Volume (T − )

  4. Temperature versus entropy ( T − S )

  5. Enthalpy versus entropy ( h − S )

  6. Pressure versus enthalpy ( P − h )
