Explanation:

• Melting is a phase change from solid to liquid, not a property of liquid water molecules themselves.
• Molecules in liquids have enough energy to vibrate, rotate, and slide past one another, which gives liquids their fluidity.
• "Getting cold" refers to a temperature change of the substance, not a behavior of individual molecules; molecular motion slows with cooling, but this is not a defining trait of liquid water molecules.

Answer:

The molecules vibrate, rotate and slide past each other.
