The bonds of that which when heavy is Deuterium cause water to expand when it freezes. The final answer: (H). <hau> Haɗin hydrogen yana sa ruwa ya faɗaɗa lokacin da ya daskare. Deuterium, ko kuma hydrogen mai nauyi, isotope ne na hydrogen, ko kuma hydrogen atom tare da ƙarin neutron. Haɗin abin da lokacin da Deuterium ke da nauyi yana sa ruwa ya faɗaɗa lokacin da ya daskare. Amsar karshe: (H).
