In summary, "sat." in thermodynamics stands for saturated, which refers to the state of a substance when it is in equilibrium between its liquid and gas phases at a specific temperature and pressure. It is closely related to the terms "vapor" and "liquid" and allows us to determine important properties such as specific volume, specific enthalpy, and specific entropy. The concept of saturation is used in various thermodynamic calculations and a substance can exist in other states such as superheated or subcooled.

It appears to be telling you that row is data for the saturation temperature.

haha I just realized it...I thought that row is parallel with -20...

1. What is the definition of "sat." in thermodynamics?

Sat. stands for saturated, which refers to the state of a substance when it is in equilibrium between its liquid and gas phases at a specific temperature and pressure.

2. How is "sat." related to other terms in thermodynamics?

"Sat." is closely related to the terms "vapor" and "liquid," as it describes the state of a substance at the point where it transitions between these two phases.

3. What does "sat." tell us about the properties of a substance?

Knowing that a substance is at its saturated state allows us to determine its specific volume, specific enthalpy, and specific entropy, which are all important properties in thermodynamics.

4. How is "sat." used in thermodynamic calculations?

The concept of saturation is used in various thermodynamic equations and calculations, such as determining the heat transfer during phase change or calculating the efficiency of a heat engine.

5. Can a substance be in a state other than "sat." in thermodynamics?

Yes, a substance can exist in states other than saturated in thermodynamics. For example, a substance can be superheated, meaning it is in a gaseous state above its boiling point, or it can be subcooled, meaning it is in a liquid state below its freezing point.
