Ts Diagrams
Nowadays the entropy values of important substances can be obtained via commercial software in tabular form or as diagrams. One of the most common diagrams is the temperature-entropy diagram (Ts-diagram). An example is Fig.2 which is the Ts-diagram of nitrogen. It gives the melting curve and saturated liquid and vapor values together with isobars and isenthalps.

Famous quotes containing the word diagrams:
“Professors could silence me then; they had figures, diagrams, maps, books.... I was learning that books and diagrams can be evil things if they deaden the mind of man and make him blind or cynical before subjection of any kind.”
—Agnes Smedley (1890–1950)
