When a substance such as ice melts, its temperature increases. Describe what happens to the arrangement of the water molecules as the temperature increases

• 
  Water molecules separate into hydrogen and oxygen atoms.

• Water molecules become less orderly and they spread apart.

• The kinetic energy of the water molecules decreases proportionally to the temperature change.

• 
  Water molecules lose all contact with one another and intermolecular forces are non-existent.
