Hlau Physical Properties:
- Lustrous (ci iab)
- Zoo conductors ntawm kub thiab hluav taws xob.
- Siab melting point.
- High ceev (hnyav rau lawv qhov loj me)
- Malleable (yuav tau hammered)
- Ductile (tuaj yeem kos rau hauv cov xov hlau)
- Feem ntau yog khoom ntawm chav tsev kub (qhov tshwj xeeb yog mercury)
- Opaque raws li ib daim ntawv nyias (tsis pom los ntawm cov hlau)
Kuj nug, 7 yam khoom ntawm hlau yog dab tsi?
Lub cev muaj zog ntawm cov hlau hlau yog lustrous, tuaj yeem , ductile , zoo conductors ntawm tshav kub thiab hluav taws xob. Lwm yam khoom muaj xws li: Lub Xeev: Cov hlau yog cov khoom khib nyiab ntawm chav tsev kub tshwj tsis yog mercury , uas yog kua ntawm chav tsev kub (Gallium yog kua rau hnub kub).
Qhov thib ob, 4 yam khoom ntawm cov hlau yog dab tsi?
- Zoo hluav taws xob conductors thiab cua sov conductors.
- Malleable - tuaj yeem raug ntaus rau hauv cov ntawv nyias.
- Ductile - tuaj yeem ncab rau hauv cov hlau.
- Muaj cov hlau nplaum.
- Opaque raws li daim ntawv nyias.
- Khoom ntawm chav tsev kub (tshwj tsis yog Hg).
Kuj kom paub yog, 10 yam khoom ntawm hlau yog dab tsi?
10 PHAU NTAWV QHIA TXOG HUAB TAIS
- Cov hlau yog malleable: - Tag nrho cov hlau tuaj yeem raug ntaus rau hauv cov ntawv nyias nrog rauj xws li. kub, nyiaj aluminium thiab lwm yam.
- Cov hlau yog ductile: - Cov hlau tuaj yeem ncab mus rau hauv cov xov hlau nyias.
- Cov hlau yog cov khoom siv hluav taws xob zoo ntawm cov cua sov thiab hluav taws xob: - Tag nrho cov hlau yog cov khoom siv hluav taws xob zoo.
Dab tsi yog 5 metallic zog?
Lub cev muaj zog cuam tshuam nrog cov cim xim hlau muaj xws li hlau luster , ci iab tsos, siab ceev, siab thermal conductivity, thiab hluav taws xob conductivity siab. Cov hlau feem ntau yog tuaj yeem thiab ductile thiab tuaj yeem deformed yam tsis muaj kev tawg.

Lub npe ntawm cov tshuaj yog dab tsi uas lub zog khaws cia nyob rau hauv thawj theem ntawm photosynthesis?
Cov kev cuam tshuam ntawm lub teeb-dependent siv lub teeb lub zog los ua ob lub molecules uas xav tau rau theem tom ntej ntawm photosynthesis: lub zog cia molecule ATP thiab txo cov khoom siv hluav taws xob NADPH. Nyob rau hauv cov nroj tsuag, lub teeb tshwm sim tshwm sim nyob rau hauv lub thylakoid daim nyias nyias ntawm organelles hu ua chloroplasts
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
