What happens during a phase change from a solid to a liquid?

1.The particles the solid vibrate faster and faster. After a while, they stop all motion.
2.The particles of the solid vibrate slower and slower. After a while, they stop moving.
3.The particles of the solid vibrate faster and faster. After a while, they can start to move around.
4.The particles of the solid vibrate slower and slower. After a while, they can start to move around.

The particles of the solid vibrate faster and faster. After a while, they can start to move around

Explanation: Solid particles movement are restricted due to the strong force of attraction between the molecules,Solid phase will only change to liquid phase if the forces of attraction holding the molecules together are broken down by heat, when this happens the solid particles movement will become more mobile as the substance is moving from solid phase and liquid phase
