A Primer on Reversible Transformations

Chemical Thermodynamics and Information Theory with Applications 

An isobaric pathway is no less special. In this case, heat is exchanged between the system and surroundings in either direction. Concomitant with the exchanges is the repositioning of the piston to maintain constant p. equates with a rectangle of area in the pV plane. Both and grec scale linearly over the transformation. 

The isotherm structure depends on the nature of the system. For an ideal gas
