PVT Surfaces Concept

Demonstrations in PVT Surfaces

3D PVT surface model with color-coded phase regions: black for Solid, yellow for Liquid and two-phase regions (Liquid & Vapor, Solid & Vapor), and red for Gas and Vapor, with labeled axes for Pressure, Volume, and Temperature

PVT Surface

A 3D model shows how pressure, volume, and temperature are interrelated for a real substance, with labeled phase regions (solid, liquid, gas) and coexistence surfaces. Students visualize how familiar 2D …

PVT Demonstrator

A piston-cylinder apparatus with projected pressure and temperature gauges demonstrates the relationship between pressure, volume, and temperature in a gas. Students observe pressure and temperature rise during compression, cooling at …
