Shenhai e fakamoʻoni fakaʻauha
ʻI he ngaahi tukunga angamaheni, ʻOku ʻikai fakaulo ʻe he efu ukamea ka ʻoku oxidation ʻi he ʻea. Neongo ia, ʻoange ʻa e ngaahi tuʻunga totonu, ʻe lava moʻoni ke combust.
Toʻo, hange ko ʻeni, ha tukunga ʻoku ke fakaulo ai ha beaker mo 50% meʻa ʻi he kava malohi. Kapau te ke fakafeʻiloaki ha lahi ʻo e efu ukamea, fakamafanaʻi ia ʻi he beaker, pea fakamovetevetea ia ʻi he holisi ʻo e beaker ʻi ha mamaʻo ʻo e senitimita ʻe ua ki he hongofulu ma nima, te ne fakaulo. Tautefito, nanoscale efu ukamea ʻoku lava ke vela ʻi he ʻea.
