Hluav taws xob yog npaj nyob rau hauv lub plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me. hlau nplaum . Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud Sib nqus teb, ob yam tshwm sim.
Thiab cov lus nug yog, dab tsi yog ib qho hlau nplaum uas ua los ntawm?
Feem ntau feem ntau hlau siv rau kev ruaj khov hlau nplaum yog hlau, npib tsib xee, cobalt thiab ib co alloys ntawm tsawg ntiaj teb hlau. Muaj ob hom kev mus tas li hlau nplaum : cov los ntawm "nyuaj" Sib nqus cov ntaub ntawv thiab cov los ntawm "mos" Sib nqus cov ntaub ntawv.
Ib yam li ntawd, peb cov khoom siv hauv tsev uas siv hlau nplaum yog dab tsi? Cov khoom siv hauv tsev uas siv cov hlau nplaum
- Tsev Suab Hais Lus. Cov neeg hais lus hauv koj lub tso suab muaj cov hlau nplaum.
- Cov Khoom Siv Hluav Taws Xob Hauv Tsev. Koj lub tshuab nqus tsev vacuum muaj lub tshuab hluav taws xob uas khiav los ntawm cov hlau nplaum.
- Txee Qhov Rooj Latch. Lub qhov rooj rau ntau lub txee tshuaj muaj cov hlau nplaum sib nqus.
- Blocks, Tsheb ciav hlau thiab lwm yam khoom ua si.
- Debit thiab Credit Cards.
Tsis tas li ntawd, dab tsi yog cov ntxhia ntau tshaj plaws uas tuaj yeem ua rau hauv cov hlau nplaum?
Magnetite
Puas yog electrons tsim magnetic teb?
Txawm tias ib tug atom electrons tsis txhob txav deb heev, lawv lub zog txaus los tsim ib qho me me magnetic teb . Txij thaum ua khub electrons tig nyob rau hauv opposite lus qhia, lawv magnetic teb thim ib leeg tawm. Nws muaj feem xyuam rau ob qho tib si magnetic teb lub zog thiab lub torque uas lub teb kev tawm dag zog.

Dab tsi yog qhov kev hloov pauv ntawm cov khoom uas txav ntawm qhov chaw mus rau qhov chaw ntawm - 12 m?
Kev piav qhia: Qhov kev txav ntawm ib qho khoom txav ntawm qhov chaw mus rau qhov chaw ntawm − 12 m yog 12 meters. Qhov kev ncua deb ntawm lub hauv paus chiv keeb mus rau qhov siab tshaj plaws txoj hauj lwm yog hu ua displacement ntawm ib yam khoom. Qhov siab tshaj plaws kev hloov pauv ntawm cov khoom nyob rau hauv ib nthwv dej yog hu ua crest thiab qhov tsawg kawg nkaus hloov pauv yog hu ua trough
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Cov qauv dab tsi thaum koj nchuav hlau filings nyob ib ncig ntawm cov hlau nplaum?
Thaum cov ntaub ntawv hlau tau nchuav ib ncig ntawm cov hlau nplaum, cov duab ntawm cov hlau nplaum raug ntes. Vim li cas qhov no tshwm sim? Tsis tas li ntawd, cov ntaub ntawv hlau no cais ua cov qauv pom tseeb ntawm cov kab
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
