(khoom, kua, roj) coexist.
Qhov kub twg ua rau txhua 3 theem sib koom ua ke?
Txhua peb txoj kab nkhaus ntawm daim duab theem sib ntsib ntawm ib qho taw tes, qhov peb npaug taw tes, qhov twg tag nrho peb theem muaj nyob hauv qhov sib npaug. Rau cov dej, qhov taw tes peb zaug tshwm sim ntawm 273.16 K (0.01ºC), thiab yog qhov ntsuas kub zoo dua li qhov dej ntawm qhov dej ntawm 1.00 atm, lossis 273.15 K (0.0ºC).
Lub siab twg ua rau tag nrho peb theem sib koom ua ke?
Lub ntsiab lus uas peb kab sib tshuam yog hu ua triple point - ntawm qhov sib xyaw ua ke ntawm qhov kub thiab txias, cov khoom muaj peev xwm xav tias ib qho ntawm peb theem. Qhov ntsuas peb npaug rau dej yog qhov kub ntawm 0.01 degrees Celsius (32.018 degrees Fahrenheit) thiab lub siab ntawm 611.7 Pascals (.
Lub xeev twg tag nrho peb theem dej sib koom ua ke?
Tus taw tes triple tshwm sim qhov twg cov khoom, kua, thiab roj hloov nkhaus sib ntsib. Lub ntsiab lus triple yog tib qho xwm txheej uas tag nrho peb theem tuaj yeem sib koom ua ke, thiab yog qhov tshwj xeeb rau txhua yam khoom siv. Dej nce mus txog nws qhov taw tes peb npaug ntawm qhov siab tshaj qhov khov (0.01 ° C) thiab ntawm qhov siab ntawm 0.006 atm.
Puas yog tag nrho peb lub xeev dej tuaj yeem sib koom ua ke?
Dej muaj nyob rau hauv peb theem sib txawv ntawm qee yam hu ua triple point. … Ntawm qee lub zog molecules yuav muaj lub zog txaus rau evaporate, txawm tias cov dej kub yog 0 degrees C. Vim yog ob qho kev cuam tshuam no nws muaj peev xwm ua rau cov dej muaj nyob hauv khoom, kua thiab roj tib lub sijhawm.
