Dab tsi yog a nqi gradient ? Yog muaj ib tug nqi gradient , nqi ntws los ntawm ntau dua concentration mus rau qis concentration, yog muaj ib tug nruab nrab ntawm lawv. Raws li tam sim no (e-) tsis zoo raug nqi , nws ntws nyob rau hauv qhov opposite direction.
Yog li ntawd, dab tsi yog txhais los ntawm hluav taws xob gradient?
Ib electrochemical gradient yog a gradient ntawm electrochemical muaj peev xwm, feem ntau yog rau ib qho ion uas tuaj yeem txav mus hla ib daim nyias nyias. Cov gradient muaj ob feem, cov tshuaj gradient , los yog qhov sib txawv nyob rau hauv cov concentration nyob rau hauv ib daim nyias nyias, thiab cov hluav taws xob gradient , los yog qhov sib txawv ntawm tus nqi hla ib daim nyias nyias.
Ib yam li ntawd, gradient hauv chemistry yog dab tsi? Tshuaj gradient . Txhais: Hais txog qhov concentration gradient ntawm ib qho ion lossis molecule. Qhov concentration gradient Tej zaum yuav muaj nyob thoob plaws ib lub cev nqaij daim nyias nyias, qhov twg cov concentration siab dua ntawm ib sab ntawm daim nyias nyias piv rau lwm sab.
Hais txog qhov no, qhov concentration gradient txhais li cas?
Txoj cai txhais ntawm a concentration gradient yog cov txheej txheem ntawm cov khoom, uas yog qee zaum hu ua cov kua nplaum, txav los ntawm kev daws teeb meem los yog roj los ntawm thaj chaw uas muaj cov khoom siv ntau dua mus rau thaj chaw uas muaj cov khoom qis dua. Cov cheeb tsam feem ntau yog sib cais los ntawm ib daim nyias nyias.
Dab tsi yog qhov txawv ntawm hluav taws xob gradient thiab concentration gradient?
Yooj yim concentration gradients yog txawv concentrations ntawm ib yam khoom nyob rau hauv ib qho chaw los yog ib daim nyias nyias, tab sis nyob rau hauv cov kab mob nyob, gradients yog complex. Cov hluav taws xob gradient ntawm K+, ib tug zoo ion, kuj nyhav tsav nws mus rau hauv lub cell, tab sis lub concentration gradient ntawm K+ nyiam tsav K+ tawm ntawm lub cell.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
Recap • Lapse Rate yog tus nqi uas kub qis dua thaum qhov siab nce hauv huab cua • Ib puag ncig lapse tus nqi yog tus nqi uas kub qis dua thaum tus nqi tsis cuam tshuam los ntawm huab cua saturation • Environmental lapse rate txo sai dua thaum huab cua tsis ruaj khov. tsis ruaj khov
Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
