Ib zoo tagnrho gas txhais tau tias yog ib qho uas tag nrho cov kev sib tsoo ntawm atoms los yog molecules zoo kawg nkaus eleastic thiab nyob rau hauv uas tsis muaj intermolecular txaus nyiam rog. Nyob rau hauv xws li ib tug gas , tag nrho cov internal zog yog nyob rau hauv daim ntawv ntawm kinetic zog thiab ib qho kev hloov hauv sab hauv zog yog nrog rau kev hloov ntawm qhov kub thiab txias.

Ib yam li ntawd ib tug yuav nug, dab tsi yog lub zog kinetic ntawm ib qho roj zoo tagnrho?

Cov lub zog sab hauv ntawm ib qho zoo tagnrho roj Qhov tshwm sim saum toj no hais tias qhov nruab nrab translational kinetic zog ntawm ib tug molecule nyob rau hauv ib tug zoo tagnrho roj yog 3/2 kT. Rau cov roj ua los ntawm ib qho atoms (cov pa roj yog monatomic, hauv lwm lo lus), lub zog txhais lus kinetic kuj yog tag nrho. lub zog sab hauv.

Tom qab ntawd, lo lus nug yog, qhov kev xav ntawm lub zog kinetic yog dab tsi? Kinetic Molecular Kev xav hais tias cov pa roj yog nyob rau hauv qhov kev txav mus tas li thiab nthuav tawm kev sib tsoo zoo kawg nkaus. Kinetic Molecular Kev xav siv tau los piav txog Charles' thiab Boyle's Laws. Qhov nruab nrab kinetic zog ntawm ib tug sau ntawm cov pa particles ncaj qha proportional rau qhov kub thiab txias xwb.

Ib yam li ntawd, qhov nruab nrab kinetic zog yog dab tsi rau ib tug monatomic zoo tagnrho gas particle?

Rau ib monatomic zoo tagnrho gas (xws li helium, neon, lossis argon), tsuas yog pab txhawb rau lub zog los ntawm translational kinetic zog . Cov nruab nrab txhais lus kinetic zog ntawm ib qho atom tsuas yog nyob ntawm qhov gas kub thiab muab los ntawm kev sib npaug: K avg = 3/2 kT.

Cov mis rau nruab nrab kinetic zog yog dab tsi?

Cov nruab nrab kinetic zog (K) yog sib npaug rau ib nrab ntawm qhov loj (m) ntawm txhua lub roj molecule lub sij hawm RMS ceev (vrms) squared.
