Cov particle nyob rau hauv ib qho khoom yog nruj nreem ntim thiab kaw rau hauv qhov chaw. Txawm hais tias peb tsis tuaj yeem pom lossis hnov nws, tus cov khoom yog tsiv = vibrating nyob rau hauv qhov chaw. Cov cov khoom nyob rau hauv cov kua yog nyob ze ua ke (kov) tab sis lawv muaj peev xwm txav /slide/flow dhau ib leeg.

Hais txog qhov no, ua li cas cov khoom yuav txav mus rau hauv cov khoom khib nyiab?

Cov khoom hauv a khov yog ib txwm tsiv . Lawv vibrate sai heev txog lawv txoj haujlwm ruaj khov. Lawv vibration speed nyob ntawm qhov kub thiab txias khov kho.

Ib yam li ntawd, muaj pes tsawg particles nyob hauv ib qho khoom? Khoom yog ib qho ntawm plaub lub xeev tseem ceeb ntawm cov teeb meem (lwm tus yog kua, roj, thiab ntshav plasma). Hauv cov khib nyiab, cov khoom tau ntim zoo.

Tsis tas li ntawd, ua li cas cov khoom coj tus cwj pwm hauv ib qho khoom?

Hauv khov kho xeev cov khoom nyob ze ua ke thiab vibrate me ntsis. Lawv muaj nyob rau hauv ib qho kev npaj tsis tu ncua - tsis muaj kev npaj nyob rau hauv lwm lub xeev. Nyob rau hauv lub xeev cov kua cov khoom tuaj yeem txav mus - qhov kev txav mus los (kub nyob ntawm) nyiam tsawg dua frantic dua hauv lub xeev gaseous.

plasma particles txav li cas?

Thaum tshav kub lub zog ntxiv rau cov roj, nws pib txav ib ncig sai. Thaum lub zog cua sov txaus ntxiv rau agas nws tuaj yeem ua ib qho ntshav ntshav . Plasma zoo ib yam li gas, tab sis nws cov khoom muaj cov qauv sib txawv thiab tus nqi. Thaum them particle txav , raws li lawv ua hauv a ntshav ntshav , lawv tsim magnetic teb.

Yuav ua li cas anti nodes tsim nyob rau hauv ib tug nyob ruaj ruaj nthwv dej?

Cov nodes thiab antinodes nyob rau hauv ib tug sawv yoj qauv (zoo li tag nrho cov ntsiab lus nyob rau hauv nruab nrab) yog tsim los ntawm kev cuam tshuam ntawm ob nthwv dej. Cov nodes yog tsim nyob rau hauv qhov chaw uas muaj kev cuam tshuam kev puas tsuaj tshwm sim. Antinodes, ntawm qhov tod tes, yog tsim nyob rau hauv qhov chaw uas muaj kev cuam tshuam tshwm sim

Yuav ua li cas cov cell membrane tuav ruaj khov nyob rau hauv cov xwm txheej?

Lub cell membrane yog lipid bilayer uas tiv thaiv qhov kev nkag ntawm dej thiab ions. Qhov no tso cai rau cov hlwb kom tswj tau ntau dua ntawm sodium ions tawm sab nraud ntawm tes. Cells kuj tseem muaj cov ntsiab lus siab dua ntawm cov poov tshuaj ions thiab cov organic acids ntawm lawv sab hauv

Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?

Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass

Dab tsi yog qhov chaw nyob ruaj khov nyob rau hauv nyias txheej chromatography?

Lub silica gel (los yog alumina) yog qhov chaw nres tsheb. Cov theem nyob ruaj khov rau nyias txheej txheej chromatography kuj feem ntau muaj cov khoom siv fluorescesin UV teeb - vim li cas koj yuav pom tom qab. Lub mobilephase yog cov kuab tshuaj uas tsim nyog los yog sib tov ntawm cov kuab tshuaj
