Yog li, thaum cov kua boiled ces nws cov molecules kis mus thiab hloov mus rau hauv roj. Qhov ntawd hu ua Evaporation . Tab sis thaum cov khoom yog rhuab (xws li dej khov, hlau los yog cov matels thiab lwm yam) yooj yim, transformation ntawm kua rau roj yog hu ua Evaporation andtransformation of solid to liquid hu ua Melting.
Ua raws li qhov no, qhov sib txawv ntawm melting thiab evaporation yog dab tsi?
Raws li lub npe qhov sib txawv ntawm vaporization thiab yaj yog tias vaporization yog ib tug hloov dua siab tshiab ntawm ib tug solidor ib cov kua rau hauv ib tug roj thaum yaj yog tus txheej txheem ntawm kev hloov lub xeev ntawm ib yam khoom los ntawm cov khoom rau cov kua los ntawm cua sov nws dhau los yaj taw tes.
qee qhov piv txwv ntawm melting yog dab tsi? Piv txwv li:
- Melting Ice rau kua dej.
- Melting ntawm hlau (yuav tsum tau kub heev)
- Melting ntawm mercury thiab Gallium (ob leeg yog kua ntawm chav tsev kub)
- Melting ntawm butter.
- Melting ntawm tswm ciab.
Ntawm no, qhov txawv ntawm melting thiab boiling yog dab tsi?
Lub ntsiab qhov sib txawv ntawm boiling point thiab yaj point yog tias qhov yaj point yog txhais asthe kub ntawm cov khoom thiab cov theem ua kua yog inequilibrium, whereas lub boiling point yog qhov kub ntawm qhov vapor siab ntawm cov kua yog sib npaug rau sab nraud.
Yuav ua li cas rau particles thaum lawv yaj?
Thaum ib qho khoom yog rhuab rau cov khoom nce zog thiab pib vibrate sai thiab sai. Cov cov khoom nyob rau hauv cov kua yog tib yam li nyob rau hauv cov khoom tab sis lawv muaj zog dua. Rau yaj lub zog muaj zog yuav tsum kov yeej theattractions ntawm lub cov khoom thiab cia lawv rub lawv sib nrug.

Yuav ua li cas xaiv tej yam ntuj tso khaws cia tej yam zoo?
Cov txheej txheem los ntawm kev ua neej nyob nrog cov cwj pwm zoo uas ua rau lawv hloov mus rau ib puag ncig kev nyuaj siab, piv txwv li, cov tsiaj nyeg, kev hloov pauv hauv huab cua, lossis kev sib tw rau zaub mov lossis phooj ywg, yuav nyiam ciaj sia thiab yug me nyuam ntau dua li lwm tus ntawm lawv hom, yog li xyuas kom cov perpetuation ntawm cov dej siab
Yuav ua li cas isotopes c12 thiab c14 zoo ib yam ntawm ib leeg?
Carbon-12 thiab carbon-14 yog ob isotopes ntawm lub caij carbon. Qhov sib txawv ntawm carbon-12 thiab carbon-14 yog tus naj npawb ntawm cov neutrons hauv lawv cov atoms. Qhov no yog li cas qhov no ua haujlwm. Tus lej muab tom qab lub npe atom qhia tus naj npawb ntawm protons ntxiv rau neutrons hauv atom lossis ion
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
Vim li cas evaporation ntawm dej yog hloov lub cev thiab tsis hloov tshuaj?
9 A. evaporation ntawm dej yog ib qho kev hloov ntawm lub cev thiab tsis yog tshuaj hloov vim nws yog ib qho kev hloov uas tsis hloov cov tshuaj xws li tshuaj hloov pauv, tsuas yog hloov lub cev. Plaub lub cev uas piav txog cov kua yog thaum nws khov, boils, evaporates, los yog condenses
