Water P–T Phase Diagram
This interactive simulator explores Water P–T Phase Diagram in Chemistry. Qualitative fusion, sublimation, vapor pressure up to critical point — probe labeled regions (pedagogical curves). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Chemistry.

How it works
Qualitative P–T diagram for H₂O: ice–liquid fusion line with negative slope, sublimation, vapor pressure up to the critical point (≈647 K, 22.064 MPa). Boundaries are stylized; move the probe to label the region.
Key equations
Clapeyron: dP/dT = ΔS/ΔV — water expands on freezing (ΔV < 0) ⇒ negative dP/dT along fusion.
