Tsuas yog li ntawd, vim li cas lub boiling point ntawm methane tsawg?

Methane muaj ib qis kub taw tes vim nws muaj zog heev intermolecular zog ntawm attraction. Cov kub point ntawm ib yam khoom yog qhov kub ntawm

Tom qab ntawd, lo lus nug yog, dab tsi yog lub xeev ntawm methane ntawm 25 degrees Celsius? gas

Cov lus nug tseem yog, puas yog ch4 muaj qhov kub siab lossis qis qis?

16 g / mol, thiab 123 g / mol, feem. Yog li ntawd, CH 4 yuav tsum muaj tus qhov kub siab tshaj plaws thiab SnH4 siab tshaj kub point . Qhov kev txiav txim los ntawm qis tshaj mus siab tshaj kub point xav tias yuav CH 4 <SnH4.

Puas yog methane muaj qhov kub siab tshaj li dej?

Dej muaj qhov kub siab dua vim hydrogen bonds uas tsim ntawm dej molecules muaj zog dua tshaj Van der Waals sib cuam tshuam nrog methane molecules, yog li ntau zog yuav tsum tau muab nyob rau hauv thiaj li yuav rhuav lub hydrogen bonds thiab tso cai rau lub dej molecules kom dim lub xeev cov kua.
