State
A substance's temperature stays constant while it changes phase, since added heat overcomes intermolecular forces instead of raising kinetic energy.
Show
Ice at 0 °C stays at 0 °C throughout melting, warming only once every bit has become liquid water.
Watch for
Heat added during a plateau is not wasted — it separates particles against intermolecular attraction, work a thermometer cannot register.
