2 Nā laʻana o nā alakaʻi a me nā mea hoʻokaʻawale
1. ʻO nā mea he mea hoʻokaʻawale uila...
A. keleawe a me ka kini
B. keleawe a me ka porcelain
C. mika a me ka kini
D. mika a me ka porcelain
Pahana
He pale maikaʻi ka mea hoʻokaʻawale uila i ke au uila, ʻoiai ʻo ka mea alakaʻi maikaʻi o ke au uila ua kapa ʻia he mea alakaʻi uila. Ma keʻano laulā, he mau mea alakaʻi uila maikaʻi nā metala, ʻoiai he mau mea hoʻokaʻawale maikaʻi nō hoʻi ka palakiko, ka laholio, ka pōhaku, ka lāʻau maloʻo, a i ʻole ka lepo maloʻo. He mau mea alakaʻi uila ke keleawe a me ka zinc, ʻoiai he mau mea hoʻokaʻawale uila ka mika a me ka porcelain.
ʻO D ka pane pololei.
2. Hiki i nā mea hoʻokaʻawale ke hana ma ke ʻano he mau alakaʻi, inā ...
Ke hoʻonui nei ʻo A.
B. kiʻekiʻe ka mahana
C. ikaika au liʻiliʻi
D. kiʻekiʻe ke anakahi uila
Pahana
He mau pale maikaʻi nā mea hoʻokaʻawale i ke au uila, ʻoiai he mau alakaʻi maikaʻi nā mea hoʻokele o ke au uila. ʻO ke au uila ka neʻe ʻana o ka uku uila ma luna o kekahi manawa.
Hiki ke hoʻoulu ʻia ka uila paʻa ma ka hamo ʻana i ʻelua mau mea hoʻokaʻawale, no ka laʻana, ka palakiko i hamo ʻia me ka lauoho a me ke aniani i hamo ʻia me ka lole. Ma hope o ka hamo ʻia ʻana, lilo kēia mau mea i mea hoʻouka uila. Lilo kēia mau mea hoʻokaʻawale i mea hoʻouka uila ma muli o ka hoʻoili ʻana o nā electrons (uku uila maikaʻi ʻole) mai kekahi mea i kekahi mea ʻē aʻe, e hana ana i kahi mea e loaʻa ai ka nui o nā electrons a lilo i mea hoʻouka maikaʻi ʻole a ʻo kekahi mea e loaʻa ka nele o nā electrons a lilo i mea hoʻouka maikaʻi ʻole.
Hōʻike nā laʻana i loiloi ʻia ma luna nei hiki i nā insulators ke hana ma ke ʻano he alakaʻi, akā i ka wā wale nō he liʻiliʻi loa ka ikaika o ke au (he liʻiliʻi loa ka nui o ka uku i hoʻoili ʻia i loko o kahi manawa i hāʻawi ʻia).
ʻO C ka pane pololei.
