Hauv daim duab dej , cov txoj kab nqes ntawm txoj kab nruab nrab ntawm cov khoom thiab cov kua dej yog tsis zoo es tsis zoo. 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.
Yog li ntawd, vim li cas txoj kab nqes ntawm fusion nkhaus yog qhov tsis zoo rau dej?
Cov melting nkhaus los yog fusion nkhaus dej khov / dej tshwj xeeb heev. Nws muaj ib nqes hav tsis zoo vim qhov tseeb tias thaum dej khov yaj, cov molar ntim qis. Cov dej khov tiag tiag yaj ntawm qhov kub qis dua ntawm qhov siab dua.
Tsis tas li ntawd, 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.
Kuj Paub, dab tsi yog qhov tshwj xeeb ntawm daim duab theem ntawm cov dej?
Phase daim duab yog graphs nrog kub ntawm ib axis thiab siab rau lwm axis. Lawv muab faib ua ntu uas qhia tias lub xeev cov khoom muaj nyob rau hauv qee qhov kev kub ntxhov thiab kub. Dej yog ncaj ncees tshwj xeeb vim nws txoj kab uas ploj lawm mus rau sab laug. Feem ntau lwm yam khoom nqes mus rau sab xis.
Dab tsi yog theem dej ntawm 1 atm thiab 0 degrees Celsius?
Ntawm qhov kub thiab txias ntawm lub ntiaj teb (cim los ntawm 'E' hauv qab) dej yog kua, tab sis nws yuav ua tau khov (uas yog, dej khov) yog tias nws qhov kub thiab txias qis dua 0 ° C thiab gaseous (uas yog, dej vapor) yog tias nws qhov kub thiab txias tau nce siab tshaj 100 ° C , nyob rau tib lub siab.
