* Gain energy: They absorb heat energy, which causes them to vibrate faster.
* Break free from bonds: The increased vibration overcomes the attractive forces (hydrogen bonds) that hold them together in liquid water.
* Increase in distance: The molecules spread out, moving further apart and becoming less dense.
* Move more freely: They have greater freedom of movement, able to move in all directions independently.
Essentially, vaporization is the process of water molecules gaining enough energy to escape the liquid phase and enter the gaseous phase.
