Ever-increasing amounts of energy (heat) were then required to bring the gold to melting point. The lasers used are called femtosecond lasers and operate on ultrafast timescales, with a ...

Consequently, a substance's melting point depends on the molecular structure of the material—for example, water melts at 0 degrees Celsius, while gold melts at just over 1000 degrees Celsius.

The melting point range of a substance is the temperature range from which the first crystal starts to melt, to the temperature at which the last crystal finishes melting. Key fact An impure ...
