Like other molecules, water molecules, H2O (or H-O-H), move, vibrate and rotate in many ways at a temperature above absolute 0. When water molecules are heated up, the total e â¦ nergy of the molecules is increased and result in moving, vibrational and rotational speeds increase. The structure of a water molecule provides a special attracting force between water molecules, hydrogen bond, to keep water molecules together.
