Hauwai (H2)

Ngā tawhā hangarau

Ko te tātai matū o te hauwai he H2, ā, ko te taumaha ngota o te ngota he 2.01588. I raro i te pāmahana me te pēhanga noa, he hau tino mura, kāore he tae, he mārama, kāore he kakara, kāore he reka, he uaua ki te rewa ki te wai, ā, kāore e tauhohe ki te nuinga o ngā matū. Heoi, i raro i te pēhanga teitei me ngā āhuatanga pāmahana ngāwari, ka tauhohe te hauwai ki te maha o ngā rauemi hauwai i roto i te tauhohenga whakatere. Ko te hauwai te hau iti rawa te matotoru e mōhiotia ana i te ao. Ko te matotoru o te hauwai he 1/14 noa iho i te hau, arā, i te 1 āhuarangi paerewa me te 0°C, ko te matotoru o te hauwai he 0.089g/L. Ko te hauwai te rauemi mata matua o te ahumahi. He nui te hauwai e hiahiatia ana e ngā ahumahi hinu me te matū. I roto i ēnei, ko te tukatuka i ngā wahie pūmua me te hanga haukini mā te tukanga Hubble ngā tono matua. Haunga te whakamahinga i roto i ngā tauhohenga matū, he whānui hoki ngā tono a te hauwai i roto i te ahupūngao me te hangarau. Ka taea te whakamahi hei hau tiaki i roto i ētahi tikanga whakarewa. He hau ahumahi nui anō hoki te hauwai, he hau motuhake hoki, ā, he whānuitia ōna whakamahinga i roto i te ahumahi hikohiko, te ahumahi whakarewa, te tukatuka kai, te karāhe mānu, te hanga matū pai, te rererangi, me ētahi atu. I taua wā anō, he pūngao tuarua pai anō hoki te hauwai (ko te pūngao tuarua e pā ana ki te pūngao me whakaputa mai i te pūngao tuatahi pēnei i te pūngao o te rā, te waro, me ētahi atu) me te wahie hau. Ka mura hei mura mārama, he uaua ki te kite. Ko te wai anake ngā Hua o te tahunga. Ka taea hoki te whakamahi i te hauwai hei rauemi mata mō te haukini hangai, te methanol hangai, me te waikawa hauwai hauwai hangai, hei kaihoko whakaiti mō te whakarewa, me te kaihoko hydrodesulfurization i roto i te whakamahine hinu. Nā te mea he hau kōpeke mura te hauwai, me penapena ki roto i te whare putunga hauhautanga, hauhautanga. Kaua te pāmahana i roto i te whare putunga e neke ake i te 30°C. Puritia kia matara atu i te ahi me ngā pūtake wera. Āraia te rā tika. Me penapena motuhake mai i te hāora, te hau kōpeke, ngā halogens (fluorine, chlorine, bromine), ngā waikura, me ētahi atu. Āraia te rokiroki me te kawe whakauru. Me ātete te rama, te hauhautanga me ētahi atu whakaurunga i roto i te rūma rokiroki ki te pahū, me ngā pana kei waho o te whare putunga, ā, me rite hoki ki ngā momo me ngā rahinga o ngā taputapu tinei ahi. Āraia te whakamahi i ngā taputapu me ngā taputapu miihini e ngāwari ana ki te mura ahi.
