    See figure 3 here: https://en.m.wikipedia.org/wiki/Thermodynamic_temperature

    As mentioned above, there are other ways molecules can jiggle besides the three translational degrees of freedom that imbue substances with their kinetic temperature. As can be seen in the animation at right, molecules are complex objects; they are a population of atoms and thermal agitation can strain their internal chemical bonds in three different ways: via rotation, bond length, and bond angle movements; these are all types of internal degrees of freedom.

    tl;dr Water be jiggly. Amount of jiggle is hard to put a number on
