Video: Cov theem ntawm cov qauv piv txwv yog dab tsi?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
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.
Ntawm no, dab tsi yog theem ntawm teeb meem piav qhia txhua?
Cov teeb meem tuaj yeem muaj nyob hauv plaub theem (lossis xeev), khov kho , ua kua , gas , thiab ntshav ntshav , ntxiv rau ob peb lwm theem siab xws li cov kua dej tseem ceeb thiab degenerate cov pa . Feem ntau, raws li ib tug khov kho yog rhuab (los yog raws li siab txo), nws yuav hloov mus rau a ua kua daim ntawv, thiab nws thiaj li yuav dhau los ua ib gas.
Ib sab saum toj no, 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.
Raws li txoj cai, tsib theem ntawm teeb meem yog dab tsi?
Tsib theem ntawm teeb meem. Muaj plaub lub xeev ntawm cov teeb meem: Khoom , kua , cov pa thiab ntshav ntshav . Lub xeev thib tsib yog neeg tsim Bose-Einstein condensates . Hauv ib khov kho , cov khoom yog ntim nruj ua ke kom lawv tsis txav ntau.
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.

Cov piv txwv ntawm kev hloov theem yog dab tsi?
Cov kev hloov pauv muaj xws li vaporization, condensation, melting, khov, sublimation, thiab deposition. Evaporation, ib hom vaporization, tshwm sim thaum cov khoom ntawm cov kua mus txog lub zog txaus kom tawm ntawm cov kua thiab hloov mus rau hauv lub xeev roj. Ib qho piv txwv ntawm evaporation yog ib lub pas dej uas qhuav tawm
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
