- Nā laʻana o nā phenomena kemika
- Nā hanana kemika i ka ʻoihana
- Ka loli o ka ikehu
- ʻIke hou aku?
ʻO ka phenomena kemikala ʻo ia nā mea e hoʻololi ai i nā mea, me ke ʻano o kekahi mau mea a me ka nalo ʻana o kekahi.
Kokoke hoʻolohe mau lākou nā hopena kemika, ka mea hiki ke maʻa wale a i ʻole ke kumu ʻia e ka hoʻohuihui ʻana i nā mea like ʻole a hoʻokau iā lākou i kekahi mau ʻano o mahana, mai pH, kaomi, a pēlā aku.
ʻO nā hopena kemika nui e kūlike i kekahi o nā ʻano aʻe:
- Hoʻohālikelike
- Hoʻolaha
- Pākuʻi
- Hoʻololi
E nānā pū: Nā laʻana o Phenomena Kino
Ka mea nui
Nui nā hanana kemika hoʻomau i ke ola o nā mea ola, e like me ka ʻohi hoʻoheheʻe i ke kanaka a me nā holoholona, ka pakanehe i nā mea kanu a me ka hanu i loko o nā mea ʻelua.
ʻO kekahi hana kemika koʻikoʻi nui, keu hoʻi i ke ola o meaolaola, ʻo ia ka fermentation, ka mea maʻa mau i ka hana ʻana i nā meaʻai e like me nā ʻaka, nā yogurts, nā waina a me nā pia.
ʻO ka ʻoiaʻiʻo ka ulu a me ka hoʻomohala ʻana o a mea ola Hoʻolohe ia i nā hōʻailona kemika e hana ʻia i loko, i kekahi manawa e hoʻoulu ʻia e nā mea o ke kaiapuni.
Nā laʻana o nā phenomena kemika
Nui nā hihia o nā phenomena kemika a i ʻole nā kaʻina hana e hoʻopili iā lākou a puni iā mākou, eia kekahi:
- Pāpopo wahie
- Wela pepa
- Kūʻai Antibiotic o ka bacteria
- Milk e huli kawa
- Hoʻomaʻemaʻe i kahi ʻeha me ka waiʻona
- Ke hoʻohana nei i ka paʻakai huaʻai e hakakā i ka ʻehaʻeha puʻuwai
- Hoʻā i kahi ihoiho
- Kāpena koko
- Ka luhi ʻana o ka mākala ma hope o ka hoʻoikaika kino
- ʻO ka make ʻana o nā kolo
- Loaʻa i ka tī Roquefort
- Loaʻa i ka cider
- Loaʻa i ka yogurt
- Hoʻolālā
- Mea hoʻolana
- Loaʻa ka bioethanol mai nā molass
- ʻO nā kini kini i pehu
- Hua manu pala
- Rusting o ka wili palaoa
- Loaʻa i ka biodiesel mai ka aila niu

Nā hanana kemika i ka ʻoihana
Eia kekahi i loko o ka ʻoihana kekahi kī phenomena. No ka poʻe hoʻomaka, ka hoʻāhu hydrocarbon e like me ka petrololina, kakolina diesel a i ʻole petrole, hānai ia i nā mīkini e lawelawe i nā hana ʻoihana he nui.
Ma ka ʻaoʻao ʻē aʻe, ʻo ka ʻoihana kila, ka pepa, nā plastics, nā mea kūkulu, nā pena, nā lāʻau, nā huahana mahiʻai, a me nā mea ʻē aʻe, hoʻokumu ʻia i nā hanana kemika like ʻole, e like me oka a, ka galvanization, ka uila uila a me kekahi poʻe ʻē aʻe.
Hoʻokumu ʻia ia ma kēia ʻano phenomena ka hanauna o nā kumu ikehu hou, e like me ka biodiesel a me ka bioethanol.

Ka loli o ka ikehu
I nā phenomena kemika he mea maʻamau ia aia ma laila loli ikehu. ʻO kahi laʻana, ua hoʻololi ʻia ka ikehu kemika i loko o nā paʻa o kekahi moleʻie i ka ikehu uila a i hoʻokuʻu ʻia paha ma ke ʻano he wela (kū kēia i nā phenotics exothermic, e like me ka hui ʻana o ka waikawa hydrochloric me ka zinc), a i ʻole hopu ʻia ka ikehu māmā a ua loli i ka ikehu kemika.
Kekahi mau hana kemika pono ka wela E hoʻokō ʻia ai, ua kapa ʻia lākou he endothermic, e koi ana kekahi i ka ke kū ʻana o nā catalist a i ʻole nā cofactors.
