Cov teeb meem feem ntau hloov lub xeev thaum koj ntxiv lossis tshem tawm cov cua sov, uas hloov qhov kub ntawm qhov teeb meem. Tam sim no cia peb tshawb txog peb txoj hauv kev uas lub xeev ntawm cov teeb meem tuaj yeem hloov pauv: khov , melting, thiab boiling.
Hauv qhov no, dab tsi yog txoj hauv kev uas teeb meem tuaj yeem hloov tau?
Cov teeb meem tuaj yeem hloov ntawm ib lub xeev mus rau lwm qhov yog tias cua sov lossis txias. Yog tias dej khov (ib qho khoom) rhuab nws hloov mus rau dej (ib kua). Qhov kev hloov no hu ua MELTING. Yog dej yog rhuab, nws hloov mus rau chav (ib pa).
Teeb meem tuaj yeem hloov nws lub xeev nrog piv txwv? Lo lus teb yog 'Yog'. Nws ua tau tiag tiag hloov nws puab, qhov loj, thiab ntim. Rau piv txwv , dej hloov mus rau hauv dej khov thaum khov, ntawm no daim ntawv ntawm cov dej hloov los ntawm cov kua xeev rau hauv cov khoom xeev ; tus teeb meem nws tus kheej tsis hloov tab sis nws transforms nws puab.
Tsis tas li ntawd, cov kev hloov pauv ntawm cov teeb meem thiab cov piv txwv yog dab tsi?
Thaum kub kev hloov , teeb meem tuaj yeem dhau mus rau theem hloov , hloov ntawm ib daim ntawv mus rau lwm qhov. Piv txwv ntawm theem kev hloov yog melting (hloov ntawm ib tug khoom mus rau ib tug kua), khov (hloov ntawm ib tug kua rau ib tug khoom), evaporation (hloov los ntawm ib tug kua mus rau ib tug gas), thiab condensation (hloov ntawm ib tug roj rau ib tug kua).
Dab tsi yog ob txoj hauv kev los hloov lub cev ntawm ib qho teeb meem?
Cov ob lub ntsiab txoj kev hloov lub cev lub cev yog los ntawm cua sov thiab txias. Piav: Lub lub cev lub xeev ntawm teeb meem tuaj yeem yog hloov los ntawm cov khoom rau cov kua lossis roj los ntawm cua sov.]

Vim li cas qee qhov kev hloov pauv tsis tuaj yeem thim rov qab?
Nws yuav ua tsis tau ntawv dua. Koj qhov siab yuav txo qis. Cov no yog cov kev hloov pauv tsis tau. Lawv tsis tuaj yeem thim rov qab txhua. Qhov sib txawv ntawm kev hloov pauv tsis tau thiab hloov tsis tau rov qab. Cov kev hloov pauv hloov tsis hloov Cov kev hloov pauv Feem ntau cov kev hloov ntawm lub cev yog hloov pauv tau. Tag nrho cov tshuaj hloov pauv yog hloov tsis tau
Dab tsi yog qhov txawv ntawm ib puag ncig kev hloov pauv thiab kev hloov pauv qub txeeg qub teg?
Qhov sib txawv ntawm cov yam ntxwv ntawm cov tib neeg ntawm tib hom yog hu ua variation. Qhov no yog inherited variation. Qee qhov kev hloov pauv yog qhov tshwm sim ntawm qhov sib txawv ntawm ib puag ncig, lossis ib tus neeg ua dab tsi. Qhov no yog hu ua environmental variation

Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
