Based on the heating curve, what happens to the particles within a substance as it changes from a liquid to a gas?

When changing to a gas, the particles within a substance break free of each other, move randomly and freely, with no defined volume.

As the temperature decreases, the particle vibrations within a substance increases, causing them to move faster and more freely.

When changing to a gas, the particles within a substance slide past each other, move randomly and freely, with a defined volume

Intermolecular forces hold the particles within the substance close together during the phase change.
