Expert Answer:

  • When a solid is heated, the particles in the solid vibrate faster and more strongly as they gain kinetic energy.

  • The molecules gain enough energy to overcome the intermolecular attractive forces.

  • The molecules then begin to break away from their fixed positions and the solid begins to melt.
