We want to see what happens to the particle's speed in a given material as the temperature changes and it faces a change of phase.
We will see that the particles in the gas (vapor of water) have a larger speed than the ones in the liquid water.
As we increase the temperature of the material, the kinetic energy of the particles that make the material increase (thus the speed increases). This causes the particles to move more, and this is why as we increase the temperature, is likely to see an increase in the volume.
Then as we increase the temperature of liquid water and that water starts to change of phase (by boiling) the kinetic energy of the particles increase, and thus, the speed increases. then the particles will be moving faster than the particles of the water in the pan.
