KOTAHI-DrerekētangaPngā kaupapa:
1. Te kaupapa o te parahi: He maha ngā wā ka whakamahia te parahi ki te hanga i ngā takirere, ngā paipa wai, ngā paipa hono mō ngā waeine hauhautanga ā-roto, ā-waho hoki, me ngā whakamahana.
2. Te kaupapa o te parahi tine: Ko te parahi tine he koranu whakarewa kore-ferrous me te iti rawa o te whakahekenga whakarewa, e whakamahia ana hei hanga whakarewa he āhua uaua, he mārama ngā āhua, ā, he iti hoki ngā whakaritenga mō te kukū o te hau. He tino ātete te parahi tine ki te waikura i roto i te hau, te wai moana, te wai māori, me te mamaoa, ā, he whānuitia te whakamahinga i roto i ngā kohua mamaoa me ngā wāhanga kaipuke.
3. Ngā kaupapa o te parahi: e whakamahia ana mō te hanga taputapu hiko pēnei i ngā whakaputa hiko, ngā pae hiko, ngā taura, ngā taputapu whakawhiti hiko, ngā whakawhiti hiko, me ngā taputapu kawe wera pēnei i ngā whakawhiti wera, ngā paipa, me ngā kaikohi papatahi mō ngā taputapu whakamahana o te rā.
E RUA - Ngā Āhuatanga Rerekē:
1. Ngā āhuatanga o te parahi: He kaha te ātete o te parahi ki te kakahu.
2. Ngā āhuatanga o te parahi tine: Mā te tāpiri i te mata ki te parahi tine ka taea te whakapai ake i tōna āheinga ki te miihini me te ātete ki te kakahu, ā, mā te tāpiri i te konutea ka taea te whakapai ake i tōna mahi whakarewa. He teitei ngā āhuatanga miihini o tēnei koranu, he mahi whakaiti kakahu, he ātete ki te waikura, he ngāwari ki te miihini, he pai te mahi whakakoi me te whakarewa, he iti te tauwehenga whakaheke, ā, kāore he aukume.
3. Ngā āhuatanga o te parahi whero: he pai te kawe hiko me te kawe wera, he tino pai te kirihou, ā, he ngāwari ki te tukatuka mā te pēhi wera me te pēhi matao.
E TORU NGĀ HANGA MATUA REREKĒ:
1. Tirohanga Whānui ki te Parahi: He koranu te parahi i hangaia mai i te parahi me te konutea. Ko te parahi i hangaia mai i te parahi me te konutea ka kiia ko te parahi noa. Mena he mea hanga mai i ngā koranu maha o ngā huānga e rua, neke atu rānei, ka kiia ko te parahi motuhake.
2. Tirohanga whānui o te parahi tine: Parahi me te tine hei huānga whakarewa matua.
3. Tirohanga Whānui mō te Parahi Whero: Ko te parahi whero, e mōhiotia ana ko te parahi whero, he matū noa iho nō te parahi, i tapaina i muri i tōna tae whero papura. He maha ngā āhuatanga ka kitea i roto i te parahi. Ko te parahi whero he parahi parakore ā-umanga, ko tōna ira rewa he 1083 ℃, kāore he panonitanga allosteric, ā, ko tōna mātotoru whanaunga he 8.9, e rima ngā wā o te konupora. Ko te taumaha o taua rōrahi he tata ki te 15% te taumaha atu i te maitai noa.
WHĀ-Mōhio atu mō te Parahi, te Parahi, te Parahi
He konganuku whero māwhero te parahi parakore, he papura te tae i muri i te hanganga o te kiriata waikura parahi i runga i te mata. Nō reira, ka kiia te parahi parakore ahumahi he parahi papura, he parahi hiko rānei. Ko te mātotoru he 8-9g/cm3, ā, ko te ira rewa he 1083°C. He pai te kawe hiko o te parahi parakore, ā, he whānuitia te whakamahinga i roto i te hanga waea, taura, paraihe, me ētahi atu; He pai te kawe wera, e whakamahia whānuitia ana hei hanga taputapu aukume me ngā mita e hiahia ana kia tiakina mai i te pokanoa aukume, pērā i te kāpehu me ngā taputapu rererangi; He tino pai te kirihou, he ngāwari ki te pēhi wera me te tukatuka pēhi matao, ka taea te hanga hei rauemi parahi pērā i te paipa, te pae, te waea, ngā rīpene, ngā pereti, ngā pepa whakarewa, me ētahi atu.
He koranu parahi te parahi, he mea hanga mai i te parahi me te konutea. Ko te parahi māmā rawa ko te koranu takirua parahi, e mōhiotia ana ko te parahi māmā, ko te parahi noa rānei. Mā te whakarerekē i te nui o te konutea i roto i te parahi ka puta he parahi me ngā āhuatanga miihini rerekē. Ko te nui ake o te nui o te konutea i roto i te parahi, ka nui ake tōna kaha, ā, ka iti ake tōna kirihou. Kāore te nui o te konutea o te parahi e whakamahia ana i roto i te ahumahi e neke ake i te 45%, ā, ki te nui ake te nui o te konutea ka pakarukaru, ka heke hoki ngā āhuatanga o te koranu.
Ko te Parahi Tin te koranu tuatahi i whakamahia i roto i te hītori, i te tuatahi e pā ana ki te parahi. Ka kiia ko te parahi nā tōna tae kikorangi hina. He nui ngā āhuatanga miihini o te parahi tine, he ātete pai ki te waikura, he whakaiti i te waku, ā, he pai te mahi whakarewa; he iti te aro ki te wera nui me ngā hau, he pai te mahi whakarewa, kāore he ferromagnetic, ā, he iti te tauwehenga whakaheke. He nui ake te ātete ki te waikura o te parahi tine i te parahi i roto i te hau, te wai moana, te wai māori, me te mamaoa.
