melting points
Solid-to-liquid thresholds
Melting points are the temperatures at which substances change from solid to liquid.
Each pure substance has a characteristic melting point—ice melts at 0°C, gold at 1,064°C.
Scientists use melting points to identify compounds and assess purity, since impurities lower the melting point.
The melting points of the samples matched, confirming they were the same compound.
