Heat & thermodynamics › Phase-transition simulator
Phase-transition laboratory
Heat, cool and compress matter to explore melting, freezing, evaporation, condensation, sublimation and latent heat.
What to notice
During a phase transition, added energy can break intermolecular bonds instead of raising temperature. This produces plateaus in a heating curve. Pressure changes transition temperatures, while nucleation barriers can permit supercooling or superheating before a new phase forms.
