P – T Diagram Exercises

 Sketch the following processes on the P -T diagram from an original state (1) to the resulting state (2):

a) The sublimation of dry ice (solid carbon dioxide),


b) A constant pressure cylinder of superheated vapor is cooled until liquid just begins to form,


c) A constant pressure cylinder of superheated vapor is cooled until all the vapor is gone,


d) A liquid-vapor two-phase mixture is heated at constant volume until its quality is 1.0









Thermodynamic Relations

Some properties like temperature, pressure, volume, and mass can be measured directly while other properties like density and specific volum...
