Hloov tus nqi hluav taws xob feem ntau ua rau kub hloov . Txawm li cas los xij, DURING lub theem hloov , qhov kub nyob twj ywm tib yam txawm tias lub zog cua sov kev hloov . Lub zog no yog coj mus rau hauv hloov tus theem thiab tsis mus nce qhov kub thiab txias.
Kuj nug, lub ntsiab lus ntawm kev hloov theem yog dab tsi?
1. theem hloov -a hloov los ntawm ib lub xeev (khoom los yog kua lossis roj) mus rau lwm qhov tsis muaj a hloov nyob rau hauv tshuaj muaj pes tsawg leeg. theem kev hloov , lub cev hloov , xeev hloov . khov, khov - tshem tawm ntawm tshav kub mus rau hloov ib yam dab tsi los ntawm cov kua mus rau ib qho khoom. liquefaction - kev hloov pauv ntawm cov khoom lossis cov roj rau hauv cov kua.
Kuj Paub, dab tsi yog cov theem hloov pauv uas tso tawm lub zog? Kev piav qhia: Muaj ob theem kev hloov pauv uas lub zog cua sov tso tawm: Condensation : Thaum cov roj condenses rau cov kua kom muaj nuj nqis ntawm lub zog hloov los ntawm cov tshuaj mus rau tshav kub hu ua Heat of Vaporization los yog Δ Hvap. Raws li cov pa roj cua txias, cov khoom qeeb qeeb, thiab cov ntaub ntawv ua kua.
Kuj Paub, qhov kev hloov pauv ntawm lub zog cuam tshuam li cas rau theem hloov?
Lawv yog kev hloov hauv kev sib raug zoo zog nruab nrab ntawm cov molecules. Yog tias cua sov tuaj rau hauv cov khoom thaum lub sijhawm a theem hloov , tiam no zog yog siv los rhuav tshem cov kev sib txuas ntawm cov molecules ntawm cov khoom. Thaum lub sij hawm melting qhov nruab nrab kinetic zog ntawm cov molecules ua tsis yog hloov.
Koj txhais li cas los ntawm theem?
Hauv chemistry thiab physics, a theem yog ib daim ntawv uas txawv ntawm lub cev, xws li khoom, kua, roj, los yog plasma. Piv txwv li, cov kua sib tov tuaj yeem muaj nyob hauv ntau yam theem , xws li roj theem thiab aqueous theem . Lub sij hawm theem kuj tseem siv tau los piav txog cov xeev sib npaug ntawm a theem daim duab.

Dab tsi yog qhov txawv ntawm lub cev thiab tshuaj hloov pauv ntawm cov teeb meem?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
Cov kev hloov pauv ntawm qhov teeb meem yog dab tsi?
Kev hloov ntawm lub xeev yog kev hloov ntawm lub cev hauv qhov teeb meem. Lawv yog cov kev hloov pauv uas tsis cuam tshuam nrog kev hloov pauv ntawm cov teeb meem tshuaj pleev lossis cov khoom siv tshuaj. Kev hloov pauv ntawm lub xeev muaj xws li melting, khov, sublimation, deposition, condensation, thiab vaporization
Dab tsi ua rau muaj qhov hloov pauv hloov pauv?
Point kev hloov. Point mutation, hloov nyob rau hauv ib tug noob nyob rau hauv uas ib tug hauv paus khub nyob rau hauv lub DNA ib theem zuj zus yog hloov. Kev hloov pauv ntawm cov ntsiab lus feem ntau yog tshwm sim los ntawm kev ua yuam kev thaum lub sij hawm DNA replication, txawm hais tias kev hloov pauv ntawm DNA, xws li los ntawm kev cuam tshuam rau X-rays lossis rau ultraviolet hluav taws xob, kuj tuaj yeem ua rau muaj kev hloov pauv
