Hlau no mas feem ntau khoom paub tias yuav nyuaj, ci iab, khaws txuas, ncaj nraim, thiab luag num. Tsis muaj hluav taws xob thiab thermal conductivity, Hlau no pab tau rau ntau cov ntaub ntawv thiab tsis tau lawv lub ntiaj teb no xwb tsis tau tib yam.
Yog koj xav impress koj cov phooj ywg nyob ib tog twg, thiab tsuav yog rau hauv"hlau,” here are some interesting facts to know.
Consider the Earth’s crust– the most abundant metal in it is aluminum. e, the Earth’s core is mostly made of iron– at least that’s what scientists think since no person has ever actually been to the core. Now when it comes to our universe, iron and magnesium are quite abundant. How cool would it be to explore other planets and see what metals are there, Sab xis? We’d probably discover ones we didn’t know existed.
As for uses on Earth, metals are vital to making things such as the bridges and skyscrapers of our cities. In the old days, there were seven metals known to mankind: gold, Tooj, silver, mercury, lead, tin and iron. Hnub no, txawm li cas los, we know about many more, including zinc and aluminum.
In America, you’re likely to find aluminum in Alabama, Arkansas thiab Georgia, qhov twg nws tshwm sim hauv av nplaum hu ua kaolin. Sab nraud ntawm Asmeskas, qhov chaw ntawm txhuas tuaj yeem pom hauv Fabkis, Jamaica thiab ib feem ntawm Africa.
Koj puas tau pom cov duab tooj liab ntawm lub tsev khaws puav pheej kos duab? Bronze yog tiag tiag ua los ntawm ob qho hlau: tooj liab thiab tin.
Hais txog kev kos duab, thaum tus pej thuam ntawm kev ywj pheej tau ua, Nws yog xim av tsis zoo, tab sis nws tig ntsuab dhau sijhawm. Qhov no tau tshwm sim vim yog cov txheej txheem hu ua oxidation whereas huab cua thiab dej cuam tshuam nrog tus pej thuam cov phaj tooj liab. Tsis txhob txhawj– qhov hloov xim tiag tiag ua rau nws muaj zog dua! Los ntawm txoj kev, tus nqi ntawm tooj liab hauv nws tuaj yeem ua 30 lab pennies.
