(1 point) The molecules of the substance move farther apart, which pulls on the intermolecular bonds between them. Heat energy forces the molecules of the substance farther apart until the rigid structure of the solid breaks. Heat energy overcomes the forces of attraction between the molecules of the substance, so the molecules can move more freely. The vibration of the molecules produces enough heat to weaken the forces of attraction between the molecules of the substance.
