A pressure–volume diagram (or PV diagram, or volume–pressure loop) is used to describe corresponding changes in volume and pressure in a system. They are...

or refrigerator is best understood by using a temperature–entropy diagram (T–S diagram), in which the thermodynamic state is specified by a point on a graph...

original piston-and-cylinder diagram used by Carnot in discussing his ideal engine. The figure at right shows a block diagram of a generic heat engine, such...

during a thermodynamic cycle is zero, it forms a closed loop on a PV diagram. A PV diagram's Y axis shows pressure (P) and X axis shows volume (V). The area...

purpose diagrams include: PV diagram T–s diagram h–s (Mollier) diagram Psychrometric chart Cooling curve Indicator diagram Saturation vapor curve Thermodynamic...

H=U+pV{\displaystyle H=U+pV\,\!} (or, in terms of specific enthalpy, specific entropy and specific volume, h=u+pv{\displaystyle h=u+pv\!} ). The diagram was...

fact that it does not make sense to refer to the work on a point in the PV diagram; work presupposes a path. There are several ways of doing mechanical work...

higher order on the pressure. Also at Boyle temperature the dip in a PV diagram tends to a straight line over a period of pressure. We then have...

inflection point in the constant-temperature line (critical isotherm) on a PV diagram. This means that at the critical point: ( ∂ p ∂ V ) T = 0 , {\displaystyle...

thermodynamics, in terms of the values of variables at the critical point. On a PV diagram, the critical point is an inflection point. Thus: (∂P∂V)C=0{\displaystyle...
