Thermodynamics: T-s Diagrams

T-s Diagrams

T-s diagrams are used to show how a change in entropy can affect the temperature of a pure substance when that substance is kept at a constant pressure or specific volume. If a T-s diagram is used to represent the process, the area under the curve will represent the heat transfer that took place during the process.

The property tables can also be used to find what the entropy of the substance is when it is at certain pressure or temperature. Equation 1 would be used to determine the entropy while the substance is a saturated mixture.
