ʻO ka ʻepekema o ke anu hohonu: ka ʻimi ʻana i nā pono o ka wai Nitrogen a me ka wai oxygen

Ke noʻonoʻo mākou i nā mahana anu, hiki iā mākou ke noʻonoʻo i kahi lā hoʻoilo, akā ua noʻonoʻo paha ʻoe i ke ʻano o ke anuanu? ʻO ke ʻano anuanu i hiki ke hoʻokuʻu i nā mea i ka manawa koke? Ma laila e komo mai ai ka waiʻona wai a me ka oxygen wai. Ma kēia blog, e ʻimi mākou i nā waiwai o kēia mau pūhui ʻelua a e ʻimi i ka honua hoihoi o ke anu hohonu.

He wai waihoʻoluʻu, ʻala ʻole, a ʻono ʻole hoʻi ka wai i hoʻolapalapa ʻia ma -195.79°C (-320°F). Hoʻokumu ʻia ia me nā molekala nitrogen i hoʻomaʻalili ʻia i kahi kūlana wai. ʻO kekahi o nā waiwai kūʻokoʻa o ka nitrogen wai, ʻo ia ka hiki ke hoʻokuʻu koke i nā mea i ka pili ʻana. He mea pono kēia no ka mālama cryogenic o nā mea olaola, e like me ka sperm, nā ʻāpana kiko, a me nā mea ola holoʻokoʻa. Hoʻohana ʻia ia i ka hana ʻana i ka fiber carbon a me ka hoʻoluʻu o nā ʻāpana kamepiula.

ʻO ka oxygen wai, ma ka ʻaoʻao ʻē aʻe, he wai uliuli hohonu, ʻono ʻole a ʻono ʻole e paila ana ma -183°C (-297°F). Hoʻokumu ʻia ia me nā molekole oxygen i hoʻomaʻalili ʻia i kahi kūlana wai. ʻAʻole e like me ka nitrogen wai, ʻoi loa ka oxygen wai a hiki ke puhi maʻalahi ma lalo o kekahi mau kūlana. He mea pono kēia i ka hoʻoulu ʻana i ka pōhaku, wili, a me ka ʻoki metala. Hoʻohana ʻia ia i ka mālama ʻana i nā maʻi hanu, e like me ka maʻi maʻi obstructive pulmonary maʻi (COPD).

I ka hoʻohui ʻana i ka nitrogen wai a me ka oxygen wai, loaʻa iā mākou kahi hui o ka oxygen nitrogen. Hiki ke pilikia kēia hui ʻana ma muli o ke ʻano o nā hopena pahū. Eia nō naʻe, i loko o nā kaiapuni i hoʻomalu ʻia, hiki ke hoʻohana ʻia ka oxygen nitrogen no nā kumu like ʻole, e like me ka cryotherapy a i ʻole ka mālama ʻana i ka ʻili. Ma kēia ʻano, hoʻopili ʻia ka hui ʻana o ka nitrogen wai a me ka oxygen wai i ka ʻili, e hōʻemi ana i nā kīʻaha koko a e hōʻemi ana i ka mumū.

E like me ka mea i ʻōlelo ʻia ma mua, hiki i ke anu hohonu ke loaʻa i kahi ʻano o nā noi, a ʻaʻole ʻokoʻa ka honua culinary. Hiki i nā kuki ke hoʻohana i ka hau hau no ka hana ʻana i nā meaʻai maloʻo, e like me ka ice cream a i ʻole sorbet, ma ka hoʻomaloʻo wikiwiki ʻana i ka hui ʻana me ka nitrogen wai. Pēlā nō, hiki ke hoʻohana ʻia ka oxygen wai no ka hana ʻana i nā ʻūhā a me nā ʻuala aerated. Hoʻohana pinepine ʻia kēia mau ʻenehana i ka gastronomy molecular e hana i nā ʻano ʻano like ʻole a me nā hōʻike.

E noʻonoʻo paha kekahi pehea e loaʻa ai iā mākou ka nitrogen wai a me ka oxygen wai, me ka noʻonoʻo ʻana i ko lākou mau wahi paila haʻahaʻa. Aia ka pane ma kahi kaʻina i kapa ʻia ʻo fractional distillation, kahi e hoʻopaʻa ʻia ai ka ea a maʻalili a lilo i wai. ʻO nā ʻāpana like ʻole o ka ea, e like me ka nitrogen a me ka oxygen, loaʻa nā wahi paila like ʻole a hiki ke hoʻokaʻawale ʻia ma o ka distillation. Pono kēia kaʻina hana i nā mea hana kūikawā a ke hana maʻamau ʻia ma kahi ʻoihana ʻenehana.

I ka hopena, ʻo nā waiwai o ka nitrogen wai a me ka oxygen wai e lilo i mau mea koʻikoʻi i nā ʻano ʻepekema like ʻole, ka lāʻau lapaʻau, a me ka kuke ʻana. Hāʻawi kēia mau mea i kahi hiʻohiʻona hoihoi i ka honua o ke anuanu hohonu a me nā hana paʻakikī e hoʻokele i ka ʻano o ka mea. Me ka hoʻomau ʻana i ka noiʻi a me ka hoʻomohala ʻana, hiki iā mākou ke ʻike i nā noi hou aku no kēia mau pūhui i ka wā e hiki mai ana.
