Peb lub xeev ntawm qhov teeb meem yog peb lub cev sib txawv uas qhov teeb meem tuaj yeem ua rau feem ntau ib puag ncig: khov kho , ua kua , thiab gas . Nyob rau hauv ib puag ncig huab, lwm lub xeev tej zaum yuav tshwm sim, xws li ntshav, Bose-Einstein condensates, thiab neutron hnub qub.
Raws li txoj cai, peb theem ntawm qhov teeb meem thiab lawv txhais li cas?
Cov peb tsim nyog theem ntawm teeb meem yog cov khoom, kua, thiab roj (vapour), tab sis lwm tus raug suav tias muaj, suav nrog crystalline, colloid, glassy, amorphous, thiab ntshav. theem . Thaum a theem nyob rau hauv ib daim ntawv yog hloov mus rau lwm daim ntawv, a theem hloov tau hais tias tau tshwm sim. xeev ntawm teeb meem Xeev ntawm teeb meem.
Ib yam li ntawd, qhov hloov pauv theem ntawm qhov teeb meem yog dab tsi? Thaum kub kev hloov , teeb meem tau undergo a theem hloov , hloov ntawm ib daim ntawv mus rau lwm qhov. Piv txwv ntawm theem hloov yog melting ( hloov los ntawm cov khoom mus rau cov kua), khov ( hloov los ntawm cov kua rau ib qho khoom), evaporation ( hloov los ntawm cov kua mus rau ib tug gas), thiab condensation ( hloov los ntawm cov roj mus rau cov kua).
Dab tsi yog cov theem ntawm cov qauv piv txwv?
Cov piv txwv zoo tshaj ntawm cov theem yog cov khoom khib nyiab , kua , thiab cov pa . Cov theem tsis paub muaj xws li: plasmas thiab quark-gluon plasmas; Bose-Einstein condensates thiab fermionic condensates; txawv txawv; ua kua siv lead ua; superfluids thiab supersolids; thiab paramagnetic thiab ferromagnetic theem ntawm cov khoom sib nqus.
4 qhov tseem ceeb yog dab tsi?
Plaub xeev ntawm teeb meem Nws tuaj yeem pom hauv lub neej txhua hnub: khoom, kua, roj, thiab ntshav.
Pom zoo:
6 theem ntawm teeb meem yog dab tsi?
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 6 qhov kev hloov pauv ntawm theem: khov, yaj, khov, vaporization, sublimation thiab deposition
Dab tsi ua rau theem hloov pauv hauv qhov teeb meem?
Hloov cov nqi hluav taws xob feem ntau ua rau muaj qhov kub thiab txias. Txawm li cas los xij, Thaum lub sij hawm hloov pauv, qhov kub thiab txias nyob twj ywm tib yam txawm tias lub zog hluav taws xob hloov pauv. Lub zog no yog coj mus rau hauv kev hloov cov theem thiab tsis mus rau hauv kev nce qhov kub thiab txias
Dab tsi theem ntawm cov teeb meem yuav siv cov duab ntawm nws lub thawv?
Ua kua Ua kom pom qhov no, yam khoom dab tsi tsis coj cov duab ntawm nws lub thawv? khov: A yam khoom uas khaws cia nws loj thiab puab tsis muaj ib thawv ; a yam khoom nws cov molecules tsis tuaj yeem txav mus los tsuas yog vibrate.
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
Kev sib raug zoo ntawm lub teeb thiab teeb meem yog dab tsi?
Lub teeb thiab teeb meem cuam tshuam rau ib leeg hauv ntau txoj hauv kev. Kev sib cuam tshuam ntawm lub teeb thiab teeb meem txiav txim siab qhov tshwm sim ntawm txhua yam nyob ib puag ncig peb. Lub teeb cuam tshuam nrog cov teeb meem xws li emission thiab nqus. Cov nyhuv photoelectric yog ib qho piv txwv ntawm qhov teeb meem absorbs lub teeb
