Which region is the water in?
Use this for “Water is at 500 kPa and 200 °C. Is it compressed liquid, a saturated mixture or superheated vapor?”

Is each state of water compressed liquid, a saturated mixture or superheated vapor?
Tap a card, then tap its group.
Compare T with Tₛₐₜ at that pressure, or v with vf and vg.
Assumptions
•
At one pressure, water boils at one temperature, Tₛₐₜ; the table lists it.
•
Below Tₛₐₜ it is compressed liquid; above it, superheated vapor; at Tₛₐₜ, a mixture.
•
By volume: v below vf is liquid, between vf and vg a mixture, above vg vapor.
