Volatiles hauv magma
Mus txog qhov chaw, siab txo qis thiab cov volatiles evolve tsim npuas uas ncig hauv cov kua. Cov npuas yog txuas ua ke ua ib lub network. Qhov no tshwj xeeb tshaj yog ntxiv cov fragmentation mus rau hauv me me tee los yog tshuaj tsuag los yog coagulate clots nyob rau hauv roj.
Yog li ntawd, dab tsi lub luag hauj lwm ua volatiles ua nyob rau hauv tiam ntawm magma?
Dej thiab lwm yam volatiles txo lub melting kub ntawm magmas . Yog li ntawd, pob zeb yuav yaj yooj yim dua nrog tsawg dua siab.
Tom qab, lo lus nug yog, yuav ua li cas tshwm sim thaum magma tsim? Melting ntawm pob zeb feem ntau tshwm sim nyob rau hauv qis lithosphere los yog sab sauv asthenosphere. Lub ntiaj teb kub zoo nkauj sai sai thaum koj khawb los ntawm lub ntiaj teb saum npoo av. Ib zaug tsim , magma migrate upwards vim nws buoyancy thiab nws thiaj li yog pub volcanoes los yog txias thiab crystallizes rau hauv intrusive. igneous pob zeb.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog volatiles hauv magma?
tsis hloov pauv . Ib qho khoom siv lossis cov khoom sib xyaw, xws li H2O lub CO2, uas tsim cov pa roj ntawm lub siab tsis tshua muaj siab thiab magmatic kub. Volatiles tuaj yeem yaj hauv silicate melts, tuaj yeem tshwm sim ua npuas ntawm exsolved gas, thiab tuaj yeem crystallize hauv cov zaub mov xws li biotite thiab amphibole.
Vim li cas dej cov ntsiab lus hauv magma tseem ceeb?
Dej Taw qhia ntawm Plate Tectonics Kev ua lub roob hluav taws yuav tsum magma , thiab ua magma xav tau cua sov. Los ntawm kev sim nws paub tias dej txo qhov melting point ntawm pob zeb. Yog dej yog nkag mus rau cov cheeb tsam sib sib zog nqus hauv ntiaj teb, ces cov pob zeb muaj zog tuaj yeem pib yaj.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
Yuav ua li cas tshwm sim thaum koj ntxiv ib tug qaug zog acid rau dej?
Thaum cov kua qaub uas tsis muaj zog ntxiv rau hauv dej, cov ntaub ntawv sib npaug sib npaug hauv cov kua qaub molecules, HA (aq), hnov mob nrog cov dej ua kua los tsim cov aqueous hydronium ions thiab aqueous anions, A-(aq). Cov tom kawg yog tsim thaum cov kua qaub molecules poob H + ions rau dej
Yuav ua li cas tshwm sim thaum dilute sulfuric acid ntxiv rau hlau sulfide?
A. Thaum twg ?dilute sulfuric acid ntxiv rau kev sib xyaw ntawm cov hlau txhaws thiab cov hmoov sulfur, cov tshuaj tiv thaiv occusrs ntawm dilute sulfuric acid thiab hlau filings uas tsim ferrous sulphate thiab evolution ntawm hydrogen. FeS tsim reacts nrog sulfuric acid los tsim ferrous sulphate thiab tso tawm hydrogendisulphide gas
