Tab sis thaum nws nyob hauv yuav luag tag nrho cov molecules hauv cov khoom muaj sia, nws yog tsis tshua muaj roj - tsawg dua ib feem ntawm ib lab los ntawm ntim. Hydrogen tuaj yeem tsim los ntawm ntau yam kev pab, xws li cov nkev, hluav taws xob nuclear, biogas thiab lub zog tauj dua tshiab xws li hnub ci thiab cua.
Puas yog hydrogen yog roj lossis kua?
Hydrogen yog lub teeb tshaj plaws. Hydrogen yog roj ntawm qhov kub ib txwmthiab siab, tab sis hydrogen condenses rau cov kua ntawm qhov rho tawm 423 degrees Fahrenheit (rho tawm 253 degrees Celsius).
Puas yog hydrogen a gas Yes los tsis yog?
Hydrogen, H, yog xim tsis muaj xim, tsis muaj ntxhiab, tsis yog xim hlau, tsis qab,cov roj kub kub heev. Nws muaj atomic loj ntawm 1.00794 amu, uas ua rau hydrogen lub lightest lub ntsiab ntawm lub sij hawm.
Puas yog hydrogen ua los ntawm roj?
Hydrogen yog roj huvuas, thaum noj hauv cov roj cell, tsuas yog dej xwb. Hydrogen tuaj yeem tsim los ntawm ntau yam khoom siv hauv tsev, xws li roj av, hluav taws xob nuclear, biomass, thiab lub zog tauj dua tshiab xws li hnub ci thiab cua.
Kuv puas tuaj yeem ua hydrogen hauv tsev?
Nws yog yooj yim ua hydrogen roj hauv tsev lossis hauv chav kuaj siv tshuaj lom neeg thiab cov khoom siv niaj hnub. Thaum koj muaj cov pa roj, koj tuaj yeem siv nws rau ntau yam kev tshawb fawb nthuav dav. Tau kawg, koj tsis yog "ua" hydrogen, vim nws yog ib qho khoom siv. Nws yog tsim los ntawm cov tshuaj tiv thaiv uas tso tawm.
