thermodynamic chart

...A chart with temperature on the horizontal axis and air pressure on the vertical axis, showing the relationship between air pressure and temperature when an air mass undergoes adiabatic change under various conditions. It is also called a thermodynamic chart. This relationship is different when the air mass is unsaturated and when it is saturated, so lines showing the equal water vapor mixture ratio when the air mass is saturated and lines showing the relationship between air pressure and temperature when the air mass undergoes adiabatic change in the saturated state are also included.

*Some of the terms that refer to "thermodynamic chart" are listed below.
