Kub yog qhov ntsuas qhov nruab nrab kinetic zog ntawm tag nrho cov molecules nyob rau hauv ib tug gas. Raws li cov kub thiab, yog li ntawd, kinetic zog , ntawm cov pa hloov pauv, RMS ceev ntawm cov roj molecules kuj hloov. Vim ceev hloov nrog kub , tus nqi ntawm diffusion ntawm ib tug roj kuj nyob ntawm tus kub.
Yog li ntawd, kinetic zog cuam tshuam li cas rau qhov kub thiab txias?
Kinetic zog yog cov zog uas ib yam khoom muaj vim nws txoj kev txav. Cov molecules nyob rau hauv ib yam khoom muaj ntau yam kinetic lub zog vim lawv tsis txhua tus txav ntawm tib qhov ceev. Raws li ib tug subtance absorbs tshav kub cov hais txav sai dua li qhov nruab nrab kinetic zog thiab yog li ntawd cov kub nce.
Tsis tas li ntawd, qhov kub thiab txias yog lub zog? Kub thiab kub muaj feem xyuam rau ib leeg, tab sis yog cov ntsiab lus sib txawv. Thaum tshav kub kub yog tag nrho zog ntawm molecular motion nyob rau hauv ib yam khoom thaum kub yog qhov ntsuas qhov nruab nrab zog ntawm molecular motion nyob rau hauv ib yam khoom.
Kuj paub, yog qhov kub thiab txias proportional rau kinetic zog?
Qhov nruab nrab kinetic zog ntawm cov roj molecules ncaj qha proportional kom meej kub nkaus xwb; Qhov no txhais tau hais tias tag nrho cov molecular motion ceases yog hais tias tus kub raug txo kom zero.
Yuav ua li cas rau kinetic zog thaum kub txo?
Thaum nruab nrab kinetic zog ntawm cov molecules nce mus (nce hauv kub ), qhov nruab nrab ceev ntawm cov molecules nce. Thiab qis nruab nrab kinetic zog ntawm cov molecules txhais tau tias lawv muaj qis dua. Txawm li cas los xij, kev hloov pauv hauv nruab nrab kinetic zog tsis ncaj qha proportional rau kev hloov hauv nruab nrab ceev.

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm kinetic thiab lub zog muaj peev xwm?
Lub Zog Muaj Peev Xwm yog lub zog khaws cia hauv ib qho khoom lossis qhov system vim nws txoj haujlwm lossis kev teeb tsa. Kinetic zog ntawm ib yam khoom yog txheeb ze rau lwm yam khoom txav thiab nyob ruaj ruaj hauv nws qhov chaw tam sim ntawd
Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?
Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
Qhov nqus thiab tso tawm ntawm lub zog cuam tshuam li cas rau qhov kub thiab txias thaum lub sij hawm muaj tshuaj tiv thaiv?
Nyob rau hauv endothermic cov tshuaj tiv thaiv cov enthalpy ntawm cov khoom yog ntau dua cov enthalpy ntawm cov reactants. Vim tias cov tshuaj tiv thaiv tso tawm lossis nqus lub zog, lawv cuam tshuam rau qhov kub ntawm lawv ib puag ncig. Exothermic cov tshuaj tiv thaiv cua sov ua rau lawv ib puag ncig thaum cov tshuaj tiv thaiv endothermic txias rau lawv
Vim li cas thiaj muaj qhov kub thiab txias thaum lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg?
Thaum lub sab qaum teb ib nrab ntawm lub ntiaj teb yog tilted mus rau lub hnub, lub sab qab teb hemisphere yog tilted. Cov neeg nyob rau yav qab teb hemisphere tau ntsib lub hnub luv luv thiab txias dua ntawm lub caij ntuj no. Thaum lub caij nplooj zeeg thiab caij nplooj ntoos hlav, qee qhov chaw hauv ntiaj teb muaj kev zoo sib xws, me me, muaj xwm txheej
Dab tsi yog cov qauv ntawm lub zog nyob rau hauv lub peev xwm thiab lub zog kinetic?
Lub zog muaj peev xwm yog khaws cia lub zog thiab lub zog ntawm txoj haujlwm - lub zog gravitational. Muaj ntau hom kev muaj peev xwm muaj zog. Kinetic zog yog kev txav - ntawm nthwv dej, electrons, atoms, molecules, tshuaj, thiab khoom. Chemical Zog yog lub zog khaws cia hauv cov khoom sib txuas ntawm atoms thiab molecules
