Volcanic iav yog lub amorphous (uncrystallized) khoom ntawm ceev ceev magma. Feem ntau, nws yog hais txog obsidian, rhyolitic iav nrog siab silica (SiO2) cov ntsiab lus. Lwm hom ntawm iav volcanic suav nrog: Pumice, uas suav tias yog a iav vim nws tsis muaj cov qauv siv lead ua.
Raws li, volcanic iav siv rau dab tsi?
Tsis ntev los no, iav volcanic ua tau siv li molecular sieve rau adsorb thiab cais luv hydrocarbons xws li propane / propylene los yog kev sib cais ntawm luv olefins (C5-C9). Xav txog cov chaw no, lub iav volcanic yog cov khoom siv uas muaj peev xwm ua tau zoo rau kev xaiv adsorption ntawm biomolecules sib txawv.
Ib yam li ntawd, volcanic iav puas yog cov ntxhia? Vim tias cov crystals tsis tuaj yeem tsim hauv qhov xwm txheej no, lava txias rau hauv ib qho iav volcanic tsis muaj crystals! Obsidian yog ntxhia -zoo li, tab sis tsis muaj tseeb ntxhia vim as a iav nws tsis yog crystalline; Nyob rau hauv tas li ntawd, nws muaj pes tsawg leeg yog heev complex kom muaj xws li ib tug ntxhia.
Tom qab, lo lus nug yog, Lava yog iav?
Lava yog tsim los ntawm crystals, volcanic iav , thiab npuas (volcanic gases). Cov kua "freezes" tsim volcanic iav . Tshuaj lava yog tsim los ntawm cov khoom silicon, oxygen, aluminium, hlau, magnesium, calcium, sodium, potassium, phosphorus, thiab titanium (ntxiv rau lwm cov ntsiab lus hauv cov ntsiab lus me me.
Koj puas tuaj yeem yaj volcanic iav?
Melting yog, casting nws tsis muaj. Obsidian yog ib qho tshuaj amorphorous uas yog hais tias nws yog iav nrog ib tug kiag li random nyob rau hauv pleev. Cov zaub mov ntawd txias maj mam thiab txhim kho lawv tus yam ntxwv siv lead ua qauv yog vim li cas lawv tsis yog optically meej.

Vim li cas daim iav convex siv los ua daim iav saib tom qab?
Convex mirrors feem ntau yog siv los ua rear-saib (tis) iav hauv tsheb vim hais tias lawv muab ib qho erect, virtual, tag nrho cov duab ploj zuj zus ntawm cov khoom nyob deb nrog kev pom dav dua. Yog li, daim iav convex ua rau tus neeg tsav tsheb pom thaj tsam loj dua li qhov yuav ua tau nrog daim iav dav hlau
Volcanic iav hu ua dab tsi?
Obsidian yog ib qho tshwm sim volcanic iav tsim los ua ib lub pob zeb extrusive igneous. Obsidian yog tsim thaum felsic lava extruded los ntawm lub roob hluav taws txias sai sai nrog kev loj hlob siv lead ua tsawg
Cov iav puas yog tshuaj lom neeg lossis lub cev hloov?
Cov txheej txheem ntawm kev ua iav cuam tshuam achemical hloov. Thaum lub cev hloov pauv piav qhia txog kev hloov pauv ntawm cov khoom ntiag tug ntawm cov khoom - zoo li cov dej khov rau hauv dej, lossis rhuav tshem ib daim ntawv - kev hloov pauv tshuaj lom neeg ntawm cov tshuaj nws tus kheej
Ob hom iav iav yog dab tsi?
Thaum lub reflecting nto yog hloov nkhaus, peb hu nws lub iav nkhaus. Muaj ob hom iav nkhaus; concave thiab convex daim iav. Cov iav nkhaus uas muaj qhov cuam tshuam ntawm qhov chaw nkhaus sab hauv yog hu ua concave mirrors thaum cov uas nws xav txog qhov chaw tawm sab nraud yog hu ua convex mirrors
Volcanic iav yog dab tsi?
Volcanic iav, ib qho iav pob zeb tsim los ntawm lava lossis magma uas muaj tshuaj lom neeg nyob ze ntawm granite (quartz ntxiv rau alkali feldspar). Xws li cov khoom molten yuav ncav cuag qhov kub thiab txias tsis muaj crystallizing, tab sis nws cov viscosity yuav dhau los ua siab heev
