Thaum qhov ntsuas kub qis dua, cov molecules muaj ntau qhov txwv ntawm kev teeb tsa thiab yog li tsim cov theem txiav txim ntau dua ( a kua). Yog hais tias qhov kub thiab txias mus ntxiv, lawv npaj lawv tus kheej hauv ib qho kev teeb tsa tshwj xeeb, ua kom muaj zog.
Lub sijhawm hloov ntawm lub xeev ua rau cov atoms lossis cov khoom ua kom ntau dua?
Txhua theem kev hloov pauv muaj lub npe tshwj xeeb, raws li qhov tshwm sim ntawm qhov teeb meem. Qhov kev txiav txim tsawg dua gas molecules xoob zog, qeeb qeeb, thiab ua ntau dua. Cov kua molecules tau txiav txim ntau tau txais lub zog, ua kom nrawm, thiab ua kom tsawg dua. evaporation tsuas yog tshwm sim ntawm qhov chaw ntawm cov kua.
Lub sijhawm hloov pauv twg cov molecules ua ntau dua thiab nruj?
Ntawm qhov tseem ceeb theem khov thiab melting sawv cev rau kev hloov pauv ntawm lub zog ntawm cov molecules ntawm cov khoom nyob rau hauv kev xav. Kev khov yog qhov hloov pauv ntawm lub zog siab mus rau ib qho ntawm lub zog qis, cov molecules txav tsawg dua thaum lawv qhov kub thiab txias. Lawv tau txiav txim ntau dua thiab kho kom zoo.
Lub sijhawm hloov ntawm lub xeev ua atoms lossis molecules txav qeeb?
Thaum ib yam khoom raug cua sov, nws tau txais lub zog thermal. Yog li ntawd, nws cov khoom txav nrawm dua thiab nws qhov kub thiab txias nce. Thaum ib yam khoom yog cooled, nws poob lub zog thermal, uas ua rau nws cov khoom txav qeeb dua thiab nws qhov kub thiab txias poob.
Yuav ua li cas yog tias atoms poob lub zog thaum hloov lub xeev?
Atoms poob lub zog raws li cov pa hloov pauv mus rau cov khoom. … Yog hais tias atoms zog thaum lub sij hawm hloov ntawm lub xeev, lawv raug rub ua ke los ntawm lub zog txaus nyiam thiab ua kom muaj kev sib koom ua ke.
