https://doi.org/10.1351/goldbook.M03821

Definition:
The conversion of a solid to a liquid by the application of heat and/or pressure.

Note: For a @LT06856@, melting occurs when the three-dimensional periodic structure of a solid collapses to give a liquid-crystal phase in which the molecules have orientational order, but not long range translational order.
