Pom ib qho tseem ceeb sib txawv ntawm tus general daim duab qhia theem thiab cov Phaj daim duab rau dej . Yog vim li cas dej yog ib yam khoom txawv txawv nyob rau hauv uas nws lub xeev yog tsawg ntom dua li cov kua hauv lub xeev. Cov dej khov ntab hauv cov kua dej . Yog li ntawd, kev hloov siab muaj qhov cuam tshuam rau ob qho no theem.

Yog li ntawd, daim duab qhia theem ntawm cov dej sib txawv li cas ntawm cov khoom seem?

Cov Phaj daim duab rau feem ntau tshuaj zoo li no. Yog li, txoj kab nqes tsis zoo qhia tias cov kua theem muaj qhov ntom ntom ntau dua li cov khoom theem . Hauv lwm lo lus, qhov ntom ntawm cov dej khov yog tsawg dua li ntawm dej . Rau feem ntau lwm yam tshuaj , cov khoom yog denser dua cov kua.

Ib yam li ntawd, daim duab qhia theem rau dej thiab carbon dioxide txawv li cas? Tsis zoo li carbon dioxide thiab feem ntau lwm yam khoom, lub daim duab qhia theem ntawm dej qhia tau hais tias qhov tsis zoo nqes rau txoj kab ciam teb ntawm cov kua thiab cov khoom hauv lub xeev. Qhov no txawv muaj ua nrog qhov tseeb ntawd dej ua tau nthuav dav raws li nws mus los ntawm cov kua hauv lub xeev mus rau lub xeev khoom.

Lub hom phiaj ntawm daim duab qhia theem yog dab tsi?

A Phaj daim duab Nyob rau hauv lub cev chemistry, engineering, mineralogy, thiab cov ntaub ntawv kev tshawb fawb yog ib hom ntawm daim ntawv uas siv los qhia tej yam kev mob (siab, kub, ntim, thiab lwm yam) uas thermodynamically txawv. theem (xws li khoom, kua los yog gaseous xeev) tshwm sim thiab coexist ntawm kev sib npaug.

Vim li cas cov kab kos duab sib txawv rau txhua yam khoom?

Thaum ntsuas qhov Phaj daim duab , nws yog tsim nyog sau cia tias cov khoom-kua theem ciam teb nyob rau hauv lub Phaj daim duab ntawm feem ntau tshuaj muaj qhov zoo nqes hav. Qhov no yog vim qhov ruaj khov theem muaj qhov ntom ntom ntau dua li cov kua, yog li ua kom lub siab ua kom lub zog melting kub.
