Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis hloov qhov teeb meem tshuaj pleev lossis tshuaj lom neeg. Cov txheej txheem koom nrog hauv kev hloov pauv hauv xeev suav nrog yaj , freezing, sublimation, deposition, condensation, thiab evaporation.

Tsis tas li ntawd, 4 lub xeev hloov pauv li cas?

Cov khoom hauv ntiaj teb tuaj yeem muaj nyob hauv ib qho ntawm plaub theem, tab sis feem ntau, lawv muaj nyob hauv ib qho ntawm peb: khoom, kua lossis roj. Kawm txog rau qhov kev hloov pauv ntawm theem: khov , yaj , condensation , vaporization , sublimation thiab tso nyiaj.

Ib yam li ntawd, dab tsi tsis hloov thaum lub xeev hloov? Cov cua sov yog siv los rhuav tshem cov kev sib txuas ntawm cov dej khov molecules thaum lawv tig mus rau hauv cov kua theem. Txij li qhov nruab nrab kinetic zog ntawm cov molecules tsis hloov Thaum lub sij hawm melting, qhov kub ntawm cov molecules tsis hloov.

Ua li no, yuav ua li cas tshwm sim thaum nws hloov lub xeev?

Teeb meem txawm poob los yog absorbs zog thaum nws kev hloov los ntawm ib xeev rau lwm tus. Piv txwv li, thaum teeb meem hloov los ntawm cov kua rau ib qho khoom, nws poob zog. Qhov txawv tshwm sim thaum teeb meem hloov los ntawm ib tug khoom mus rau ib tug kua. Rau ib tug ruaj rau hloov mus ua kua, teeb meem yuav tsum nqus lub zog ntawm nws ib puag ncig.

Yuav ua li cas hloov lub xeev?

Kev hloov ntawm lub xeev yog lub cev kev hloov hauv qhov teeb meem. Lawv yog reversible kev hloov uas tsis ua hloov teeb meem tshuaj pleev los yog tshuaj lom neeg cov khoom. Cov txheej txheem koom nrog kev hloov ntawm lub xeev muaj xws li melting, freezing, sublimation, deposition, condensation, thiab evaporation. Lub zog yeej ib txwm koom nrog kev hloov ntawm lub xeev.
