    Based on the posed question and its limiting conditions, elemental mercury is a correct answer. Pure hydrogen peroxide or isopropyl alcohol would qualify, too.

    If you include materials which are liquid outside of “room temperature,” things like magma and liquid nitrogen would also be correct answers.
