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.
