Answer:
The correct answer is The particles move more quickly.
Explanation:
When we heat water, the molecules slide side by side causing their bonds to break as a consequence of the motion energy (kinetic energy) of the water molecules due to the heat it contains.
When water boils, the increased kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows the water molecules to escape very quickly into the air as a gas. We can observe this gas as water vapor.
Given this information, we can say that the correct answer is The particles move more quickly.
