Nā mea hoihoi e pili ana i nā metala

Nā mea hoihoi e pili ana i nā metala He manawa kūpono loa e aʻo hou aʻe e pili ana i nā mea i hoʻohana ʻia i ka ʻoihana a me nā hana kūloko. ʻOkoʻa lākou i ka ikaika, waiwai, conductivity mehana a me nā ʻano ʻē aʻe he nui. Kūlohelohe kekahi o lākou, ʻoiai e ʻeli ʻia nā kemika.

No laila, eia nā mea hoihoi loa e pili ana i nā metala.

1. ʻO ke kālā ka minela kahiko loa. I ka wā o ka ʻeli ʻana i ka archaeological, ua hoʻomalu ka ʻepekema i nā mea kālā i moe i ka honua no 6 mau makahiki.
2. I ka ʻoiaʻiʻo, ʻo nā mekala 'Olumepika "gula" 95-99% i hana ʻia i ke kālā.
3. ʻO nā kaʻe o nā moni, kahi papaʻu papau - nā apo, aia i ko lākou ʻano i ke kanaka akamai ʻo Isaac Newton, ka mea i hana no kekahi manawa ma ka Royal Mint o Great Britain (e ʻike i nā mea hoihoi e pili ana iā Great Britain).
4. Hoʻomaka ka hoʻohana ʻia ʻo Gurts i ke kālā e hakakā me nā mea hoʻopunipuni. Mahalo i nā notch, ʻaʻole hiki i nā crooks ke hōʻemi i ka nui o ke dālā, i hana ʻia me nā metala makamae.
5. I ka mōʻaukala holoʻokoʻa o ke kanaka, ua ʻeli ʻia ma kahi o 166,000 mau tona o ke gula, a ʻo ke ana kuapo o kēia lā ua like ia me $ 9 trillion. Eia nō naʻe, ʻōlelo nā ʻepekema aia ma kahi o 80% o ka hao melemele e loaʻa mau nei i loko o ka ʻōpū o ko mākou honua.
6. ʻIke paha ʻoe i kēlā me kēia 45 mau minuke e like me ka nui o ka hao i lawe ʻia mai ka ʻōpū o ka honua e like me ka mea i eli ʻia ai ke gula i ka mōʻaukala?
7. ʻO ka hoʻohui ʻana o nā kāhiko gula i nā impurities o keleawe a kālā paha, inā ʻaʻole palupalu.
8. ʻO kahi mea hoihoi ʻo ia ka mea kiʻi ʻoniʻoni Palani ʻo Michel Lotito i kaulana i ke ʻano he kanaka nāna i ʻai i nā mea "hiki ʻole ke inu". Aia kahi mana i kāna mau hana i ʻai ai i ka nui a i 9 tone o nā metala like ʻole.
9. ʻO ke kumukūʻai o ka hana ʻana i nā kālā Lūkini āpau, a i 5 rubles, i ʻoi aku i ko lākou alo. ʻO kahi laʻana, ka hana ʻana o 5 kopecks i nā kumukūʻai he 71 kopecks mokuʻāina.
10. No kahi lōʻihi o ka manawa, kūʻai ʻia ka platinum i 2 mau manawa ma lalo o ke kālā a ʻaʻole hoʻohana ʻia ma muli o ka refractoriness o ka hao. E like me kēia lā, ʻo ke kumukūʻai o ka platinum he mau haneli mau manawa ke kumu kūʻai o ke kālā.
11. ʻO ka metala māmā ka lithium, nona ka hapalua hapalua o ka wai.
12. He pīhoihoi ia i ka manawa o ke alumini pipiʻi loa (e ʻike i nā ʻike hoihoi e pili ana i ka alumini), ʻo kēia lā ka mea hao maʻamau o ka honua.
13. I kēia manawa, manaʻo ʻia ka titanium ʻo ka mea hao paʻa loa ma ka honua.
14. Hōʻoia ʻepekema ʻoiaʻiʻo make ke kālā i ka bacteria.
