As more thermal energy is added to the substance, its particles gain enough thermal energy to move around more freely. The particles remain close together, but they are able to slide past one another. When all of the particles have broken out of their fixed positions, the substance has changed state. Which of the following happen during this change of state?

• the particles have more energy

• the particles have less energy

• the number of particles decrease

• the number of particles increase
