If we want to follow changes in volume, we may construct P-v or T-v diagrams, in which we hold temperature (T) or pressure (P) constant. Let us consider the case of a P-v Diagram (Figure \(\PageIndex{4}\)). Figure \(\PageIndex{4}\): P-v Diagram For A Pure Component

During a phase transition, both pressure and temperature must remain constant for pure components. Now, if we want to generate all the possible points that make up the vapor pressure curve in Figure 3.2, we would need to repeat the experiment for different temperatures.

The equilibrium state of a pure substance and its phase transitions are commonly illustrated in phase diagrams. Figure 2.3.1 is a three-dimensional [latex]P-v-T[/latex] phase diagram, where the three axes are pressure, specific volume, and temperature, respectively.

This log pressure versus log volume phase diagram illustrates phase behavior of a single component (water) and the concept of state functions. Use sliders to move the black dot at constant pressure or constant volume.

Feb 1, 2023 · A pressure-volume (PV) diagram is a graphical way of representing the relationship between the pressure and volume of an ideal gas. A PV diagram is drawn for a thermodynamic process occurring in a closed system, where there is no exchange of matter and energy between the system and its surroundings.

Jul 10, 2021 · Phase transitions: phases of matter, PV diagrams, isotherms (ideal gas law & van der Waals), critical temperature, Maxwell’s construction, latent heat (converting ice into steam). For more related figures, please see the Thermodynamics category.

A pressure–volume diagram (or PV diagram, or volume–pressure loop) [1] is used to describe corresponding changes in volume and pressure in a system. They are commonly used in thermodynamics, cardiovascular physiology, and respiratory physiology.

Our next step, in order to continue this discussion in a coherent manner, is to draw the complete P-V diagram for this binary mixture by delineating the two-phase region. In the same way as we did previously, we delineate the two-phase region by drawing a complete family of isotherms in the P-V diagram.

look at PV diagrams. A PV diagram is a graph of Pressure as a function of Volume. There are four different situations that you can expect to see shown in PV diagrams: 1. Isobaric: the gas is held at a constant pressure 2. Isochoric: the gas is held at a constant volume 3. Isothermal: the gas is held at a constant temperature 4.
