Phase Diagram Features
Features of a phase diagram:
- Triple point: temperature and pressure at which all three phases are in equilibrium.
- Vapor-pressure curve: generally as pressure increases, temperature increases.
- Critical point: critical temperature and pressure for the gas.
- Melting point curve: as pressure increases, the solid phase is favored if the solid is more dense than the liquid.
- Normal melting point: melting point at 1 atm.
