Naikokene nuʻa

Naikokene - Nine Inch hehee ai o ka papa'āweʻaweʻa kemika'ōnaehana, i hoʻokohu 'ia e nā palapala N, a me ke kaʻina, helu 7. Aia ka he lātoma N2, iloko olaila o elua nā'ātoma. Kēia Nine Inch He He colorless, odorless a me ka tasteless kinoea me ia mea inert ma lalo o maʻamau ana. I ka pa apŘ o ka naikokene ma lalo o maʻamau rula (ma 0 ° C a me ka puʻe o 101,3 kPa) mea like i 1.251 g. / Dm3. Ke hehee ai ka mahele ana o ka honua i ka lewa i loko o ka nui o 78,09% o kona buke. Ua Ua mua loaa like i ke keʻena o ka lewa Hawaiian kauka Daniel Rutherford i ka 1772.

Wai naikokene mea he cryogenic wai. Ma ka lewa puʻe mea maʻi hēhē ma - 195,8 ° C. No laila, ka mea hiki ke waiho wale i ka noho kaʻawale moku, a he kila poʻina nalu no liquified kinoea a Dewar alabata. Wale i keia hihia ka mea, hiki ke waiho waho a kaʻi aku me kekahi poho ma muli o ka omoāea. Like maloo hau (liquefied i carbon dioxide, ole i ike ia e like me ke kalapona'okikene lua), kinowai naikokene ua hoʻohana 'ia e like me ka refrigerant. Eia hou, ka mea, ua hoʻohana 'ia no ka cryopreservation o ke koko, reproductive aeee (sperm a me ka hua) e like me nā liluwelo Eia kekahi laʻana a me nāʻano makelia hou. He koi, a me ka lapaʻau hana, no ka laʻana i cryotherapy i ka wehe cysts a me warts ma luna o kaʻili. wai naikokene paʻapū lākou, 0,808 g. / cm3.

He nui industrially nui i huiʻia e like me nitricʻakika, ammonia, ke aloha nitrates (pahū, mōʻalihaku) a me cyanides hoʻohui pū N2. Loa ikaika makaukau na kaula paa elemental naikokene i loko o ka lātoma ke kumu hihia no kona komo i loko o Nine Inch reactions, ia mea ma muli o ka 'oni' kona ma lalo o maʻamau kūpono (ka mahana a me ka puʻe). Me kēia mau kumu N2 mea o ka nui o na mea he nuiʻepekema a me ka hanalima kihapai. No ka laʻana, ka mea, ua pono e malama i ma situ puʻe i loko o ka pōʻalo o ka aila a me ke kinoea. Kekahi kona mea hiki ole akeakamai noi pono ka mea i ka pa apŘ o ka naikokene i ka ua puʻe a me ka wela i ka ike. Mai nā kānāwai o ke kālaikūlohea a me thermodynamics ka mea, uaʻike ia i mau ka leo me ka hoomahuahua i ana wela, e hoonui i ka manaʻo koikoi a me ka pa apŘ o ke kinoea, a me ka hope versa.

I ka wa a ke kumu hana, ua pono, e ike i ka paʻapū o ka naikokene? I ka ho omaulia ana o keia aiao ua hoʻohana 'ia ka wā ke hoʻololi i keʻano o ka hanaʻana i hana ka hoʻohana' ana N2, i loko o ke keʻena hoʻokolohua, a ma ka manufacturing. E ho ohana i ka ike waiwai o ka pa apŘ o ke kinoea, he mea hiki, e hoʻomaulia i ka nui o ka kekahi leo. No ka laʻana, ka mea, ua ikeia e lawe i ke kinoea ka leo ma lalo o maʻamau olelo o 20 dm3. Ma keia hihia, ua hiki ke ho omaulia kona nuipa a: ka m = 20 • 1,251 = 25,02 g. Inā nā kūlana oko mai o ka hae, a ua ikeia no ka nui o N2 ma lalo o kēia mau rula, oe, e pono i mua loaʻa (no nā palapala kuhikuhi), i ka pa apŘ o ka naikokene ma ka kekahi puʻe a me ka wela, keia nui ua laila hoonuiia e ka buke e ku ma ke kinoea.

Na helu i lawe mai ma luna o ka? Iecaianoaaiiie i loko o ka makaukau ana o nā mea kaupaona o ke kaʻina huahelu. Ka mea, e pono no i ka hana o keʻanoʻenehana keʻano o ka hanaʻana, koho o ka instrumentation, i ka ho omaulia ana o oaoieei-yeiiiie? Aneiai kiko'î, a oi. No ka laʻana, ma hope o noho a pau Nine Inch? Iecaianoaaiiuo i hoʻomākaukauʻia a me nāʻohe pono mua e komo ai, a me ka maʻi e e ho'āla hou aʻelaʻo ka hoomaemaeia me ka inert kinoea - naikokene (ka mea, o ka makepono a me ka loa i loaʻa ma mua, no ka laʻana, helium a argon). Nō kāu, ka mea, e puhi i loko o ia ka nui N2, i mea mau manawa o ka buke o ke kaa a pipelines, i ke ala wale e wehe mai i ka'ōnaehana o flammable kinoea, a ma ka ohu a me ka hoʻopau i ka Naita me ia a me ke ahi. Hoʻolala i ka noho ana ma mua? Aiiio, technician, e ike ana i ka buke a me ka pa apŘ o ka'ōnaehana ua kahe aku la ia o ka naikokene, N2 ho omaulia i ke nuipa a, a ua koi 'ia no ka puhi.

E Nohie na ho, i mai ole koi miomio, maoli kinoea equate i ka maikaʻi kinoea, a hoʻohana Avogadro ka kānāwai. Mai ke kaupaona ana o 1 Mol o N2 heluna hapauuku like me 28 nā huna, a me 1 kameleona o kekahi buke o ka maikaʻi kinoea ninoaaeyao 22,4 nā lika, ka naikokene nuʻa mea like i 28 / 22,4 = 1,25 nā huna / hano = 1,25 g. / Dm3. Kēia papa hana i pili i ka koke huli i ka nuʻa no kēlā me kēia kinoea,ʻaʻole wale nō N2. Ua Ua pinepine hoʻohana 'ia i loko o mākau keʻena hoʻokolohua.
