Cov pa roj carbon dioxide
"Cov pa roj carbon dioxide yog cov tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj kuab lom. Melting point -56.6 ° C (0.52MPa), boiling point -78.6 ° C (sublimation), ceev 1.977g / L. Cov pa roj carbon dioxide muaj ntau yam. industrial siv.
Cov dej khov qhuav yog tsim los ntawm liquefying carbon dioxide rau hauv cov kua uas tsis muaj xim nyob rau hauv ib lub siab, thiab tom qab ntawd sai sai solidifying nyob rau hauv qis qis. Nws qhov kub yog -78.5 ° C. Vim nws qhov kub thiab txias heev, cov dej khov qhuav feem ntau yog siv los khaws cov khoom khov los yog cryogenic.
