BuzzFeed Staff Because This is the definition of phase diagram along with an illustration of a typical diagram. A phase diagram is a chart showing the thermodynamic conditions of a substance at different pressures and temperatures. The regions around the lines sh A phase diagram allows you to observe how a substance's temperature and pressure results in various physical states of matter.

The change in enthalpy is a fancy term for the change in thermal energy of the system at constant pressure. Typically we classify reactions as either endothermic or endothermic. 4.88 pressure-enthalpy diagram for ethylene 10 100 1000 10000 700 750 800 850 900 950 1000 1050 1100 1150 1200 enthalpy, Btu/lb pressure (psia) 160 F 140 F 120 F 100 F 80 F 60 F 40 F 20 F 0 F 20 F 240 F 200 F 100 F 0 F 100 F 200 F 300 F liquid liquid-vapor two phase vapor psia = pounds per square inch absolute This Demonstration shows a pressure-enthalpy () diagram for water.

Check and uncheck the boxes to add or remove a property from the diagram. You can show lines of constant vapor quality (blue), temperature (green), density (orange, dashed) and entropy (purple, dashed). You can show grid lines using a checkbox. The Mollier diagram, also called the enthalpy (h) – entropy (s) chart or h-s chart, is a graphical representation of thermodynamic properties of materials. In general, it is a relationship between enthalpy (measure of the energy of a thermodynamic system), air temperature, and moisture content. Change in enthalpy is calculated rather than enthalpy, in part because total enthalpy of a system cannot be measured since it is impossible to know the zero point.

The enthalpy H of a thermodynamic system is defined as the sum of its internal energy U and the work required to achieve its pressure and volume: H = U + pV, where p is pressure, and V is the volume of the system. Enthalpy is an extensive property; it is proportional to the size of the system (for homogeneous systems).

The Carnot factor-enthalpy diagram has been used extensively for the second law analysis of heat transfer processes [5,6]. With enthalpy variation (heat) as the abscissa and the Carnot factor as the ordinate the area between the special curves, representing the heat exchanging media on this diagram, illustrates the exergy losses due to the
