Nto nro, capillary nkaus, thiab viscosity yog cov khoom tshwj xeeb ntawm kua uas nyob ntawm qhov xwm txheej ntawm kev sib cuam tshuam intermolecular. Nto nro yog lub zog yuav tsum tau ua kom qhov chaw saum npoo ntawm a ua kua los ntawm tus nqi muab.
Xav txog qhov no, dab tsi yog cov khoom ntawm cov kua?
Cov kua dej coj ntawm cov duab ntawm lawv lub thawv. Cov ua kua Lub xeev ntawm cov teeb meem yog ib theem nruab nrab ntawm cov khoom thiab cov pa. Zoo li cov khoom ntawm cov khoom, cov khoom hauv ib ua kua yuav raug cuam tshuam rau kev sib txuas lus; txawm li cas los xij, ua kua particles muaj ntau qhov chaw nruab nrab ntawm lawv, yog li lawv tsis tas nyob rau hauv txoj hauj lwm.
Ib sab saum toj, dab tsi yog 4 yam khoom ntawm cov kua? Cov kua yog cov kua dej uas tsis muaj zog uas ua tau raws li cov duab ntawm nws lub thawv tab sis khaws cia (ze li) tas li. ntim ywj siab ntawm siab. Yog li ntawd, nws yog ib qho ntawm plaub lub hauv paus ntsiab lus ntawm qhov teeb meem (lwm tus yog khoom, roj, thiab ntshav), thiab yog tib lub xeev uas muaj qhov tseeb. ntim tab sis tsis muaj qhov ruaj khov.
Cov neeg tseem nug, 3 yam khoom ntawm cov kua yog dab tsi?
Cov molecules tsis muaj ntau qhov chaw nruab nrab ntawm lawv. Cov molecules tsis tuaj yeem nyem ze rau ib leeg. Cov kua dej muaj qhov ntim ruaj khov tab sis tsis muaj qhov ruaj khov. Lawv muaj qhov ntim ruaj khov tab sis lawv tsis muaj qhov ruaj khov lossis qhov tseeb.
