When water evaporates
vladimir1956 [14]

c) The motion of water molecules causes them to leave the liquid and become a gas

Explanation:

When water evaporates, the motion of water molecules causes them to leave the liquid and become a gas. Evaporation is merely a phase change in which liquids changes to solid.

  • During the process of evaporation, heat energy causes the motion of the particles or molecules to increase.
  • This will then break the intermolecular forces holding them together leading to more freedom of the molecules.
  • The molecules will then move from being liquids to solids.
