Hydrogen yog cov khoom siv tshuaj nrog lub cim H thiab tus lej atomic 1. Hydrogen yog lub teeb tshaj plaws. Ntawm cov txheej txheem hydrogen yog cov pa roj ntawm diatomic molecules muaj cov qauv H₂. Nws yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab kub kub heev.
Puas yog qhov melting ntawm hydrogen siab lossis qis?
Hydrogen muaj thib ob qis tshaj qhov kub hnyiabthiab cov ntsiab lus melting ntawm tag nrho cov tshuaj, thib ob tsuas yog helium. Hydrogen yog cov kua hauv qab nws qhov kub ntawm 20 K (-423 ºF; -253 ºC) thiab cov khoom hauv qab nws cov ntsiab lus melting ntawm 14 K (–434 ºF; -259 ºC) thiab atmospheric siab. Pom tseeb, cov kub no qis heev.
Puas yog hydrogen H2 lossis H?
Hydrogen yog lub ntsiab lus ntau tshaj plaws hauv ntiaj teb thiab nws muaj tus lej atomic ntawm 1. Hydrogen muaj molar loj ntawm 1 thiab nws cov mis molecular yog H2. Hydrogen, H, yog lub teeb ci tshaj plaws nrog tus lej atomic 1. Nws yog xim tsis muaj xim, tsis muaj ntxhiab, tsis qab, thiab cov pa taws heev nrog cov mis molecular H2.
Lub melting point ntawm hydrogen hauv Kelvin yog dab tsi?
