What happens to the particles during boiling?
They slow down.
They stop moving.
They gain enough energy to overcome the forces holding them together.
They increase their kinetic energy and decrease the forces holding them together.
Explanation
Boiling requires adding energy, and the particles gain enough energy to overcome the attraction holding them in liquid form and start to escape as gas.
