The conversion of a solid to a liquid by the application of heat and/or pressure.
Note:
For a
liquid crystal, 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.
