Crystals feem ntau tsim nyob rau hauv cov xwm thaum cov kua txias thiab pib harden. Qee cov molecules hauv cov kua sib sau ua ke thaum lawv sim ua kom ruaj khov. Lawv ua qhov no nyob rau hauv ib tug uniform thiab rov ua qauv uas ua rau cov siv lead ua . Hauv qhov xwm txheej, siv lead ua tuaj yeem tsim thaum cov pob zeb ua kua, hu ua magma, txias.
Ib yam li ntawd, dab tsi yog crystal kid txhais?
Cov me nyuam txhais ntawm siv lead ua (Nrawm 1 ntawm 2) 1: quartz uas tsis muaj xim thiab meej lossis ze li ntawd. 2: Lub cev tsim los ntawm cov khoom tawv tawv kom nws muaj qhov chaw tiaj tus nyob rau hauv ib qho kev npaj txawm tias dej khov siv lead ua ib ntsev siv lead ua . 3: lub iav tsis muaj xim ntshiab uas zoo heev.
Qhov thib ob, koj yuav ua li cas ua crystals rau cov menyuam yaus? Loj hlob Crystals nrog Borax
- ½ quart (2 khob) canning hub los yog kub kub ruaj khov ntsuas khob.
- 1 ¾ khob dej kub heev (Kuv siv yuav luag boiling-tab sis ceev faj heev)
- 1/3 khob borax.
- yeeb nkab ntxuav / chenille qia, txiav nyob rau hauv ib nrab.
- txoj hlua.
- daim kab xev los yog xaum.
Yog li ntawd, dab tsi yog gemstones rau cov me nyuam?
Gemstone yog pob zeb, pob zeb (raws li hauv lapis laj ) lossis petrified cov ntaub ntawv uas thaum txiav thiab polished yog sau los yog siv tau nyob rau hauv jewellery. Lwm tus yog cov organic, xws li amber (fossilised tree resin) thiab dav hlau (ib daim ntawv thee).
Cov no suav nrog:
- Agate.
- Alexandrite.
- Amethyst.
- Aquamarine.
- Beryl.
- Citrine.
- Garnet.
- Olivine.
Dab tsi yog science tom qab ntsev crystals?
Raws li cov dej evaporates los ntawm cov tshuaj, cov Na thiab Cl atoms pib sib txuas ua ke, ua ntej ua ib qho molecules thiab tom qab ntawd cov molecules sib txuas ua ke, tsim. siv lead ua . Txhua lub molecule yuav tsim tib lub cev siv lead ua txhua zaus nws tsim. Cov siv lead ua puab rau ntsev yog lub voos xwmfab zoo li 6 sab tuag.

Koj piav qhia txog hluav taws xob zoo li cas rau cov menyuam kawm ntawv preschool?
Tus nqi zoo li qub tshwm sim thaum ob qhov chaw kov ib leeg thiab cov electrons txav ntawm ib qho khoom mus rau lwm qhov. Ib qho ntawm cov khoom yuav muaj tus nqi zoo thiab lwm qhov tsis zoo. Yog tias koj rub ib yam khoom sai sai, zoo li lub zais pa, lossis koj txhais ko taw ntawm cov ntaub pua plag, cov no yuav tsim cov nqi loj heev
Koj piav qhia txog photosynthesis li cas rau cov menyuam kawm ntawv preschool?
Photosynthesis - Lub voj voog ntawm cov nroj tsuag thiab lawv ua li cas lub zog! Lub hnub (lub teeb lub zog), dej, minerals thiab carbon dioxide yog absorbed los ntawm cov nroj tsuag. Cov nroj tsuag ces siv lawv los ua cov piam thaj / qab zib, uas yog lub zog / khoom noj rau cov nroj tsuag
Koj piav qhia txog av qeeg rau tus menyuam li cas?
Av qeeg tshwm sim thaum ob daim loj ntawm lub ntiaj teb crust dheev plam. Qhov no ua rau muaj kev poob siab tsis ua rau co lub ntiaj teb nyob rau hauv daim ntawv ntawm av qeeg. Av qeeg tshwm sim qhov twg? Av qeeg feem ntau tshwm sim ntawm cov npoo ntawm qhov loj ntawm lub ntiaj teb crust hu ua tectonic daim hlau
Koj piav Newton txoj cai thib ob rau cov menyuam li cas?
Txoj cai thib ob hais tias qhov loj dua ntawm ib qho khoom, qhov ntau zog nws yuav siv sij hawm kom ceev cov khoom. Tseem muaj qhov sib npaug uas hais tias Force = huab hwm coj x acceleration lossis F = ma. Qhov no kuj txhais tau hais tias qhov nyuaj koj ncaws pob qhov deb nws yuav mus
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
