Cov nruab nrab kinetic zog ntawm ib tug sau ntawm cov pa particles yog ncaj qha proportional kom tsuas yog kub.
Kuj nug, puas yog lub zog kinetic ncaj qha proportional rau kub?
Qhov nruab nrab kinetic zog ntawm cov roj molecules yog 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.
Qhov thib ob, qhov nruab nrab kinetic zog yog dab tsi? Kinetic Zog thiab Nruab nrab Ceev Raws li kub thiab nruab nrab kinetic zog nce li ntawd nruab nrab ceev ntawm huab cua molecules. 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.
Ua li no, qhov kev sib raug zoo ntawm nruab nrab kinetic zog thiab kub yog dab tsi?
Kinetic zog yog cov zog uas ib yam khoom muaj vim nws txoj kev txav. Cov molecules hauv ib yam khoom muaj ntau yam kinetic zog vim lawv tsis txhua tus txav ntawm tib qhov ceev. Raws li ib tug subtance absorbs tshav kub, hais mus sai sai lub nruab nrab kinetic zog thiab yog li ntawd cov kub nce.
Qhov ntau npaum li cas yog ncaj qha proportional rau lub zog kinetic ntawm cov khoom hauv cov pa roj?
kub

Dab tsi yog proportional ncaj qha rau zaus?
Lub teeb tuaj yeem xav tias yog "particle" ntawm electromagnetic zog hu ua photons. Txij li thaum lub zog nce raws li qhov zaus nce, lub zog yog ncaj qha proportional rau qhov zaus. Vim tias zaus thiab wavelength muaj feem cuam tshuam los ntawm qhov tsis tu ncua (c) lub zog kuj tuaj yeem sau rau hauv cov ntsiab lus ntawm wavelength: E = h · c / λ
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
Lub hnub ncaj qha thiab tsis ncaj qha cuam tshuam li cas rau qhov kub thiab txias?
Lub hnub ncaj qha los tsoo lub ntiaj teb saum npoo ua rau muaj qhov kub thiab txias dua li lub hnub ci ncaj qha. Lub hnub ci dhau los ntawm huab cua tab sis tsis sov nws. Tsis tas li ntawd, lub teeb lub zog los ntawm lub hnub tsoo cov kua thiab cov khib nyiab ntawm lub ntiaj teb. Lub hnub ci poob sib npaug ntawm lawv txhua tus
Qhov nruab nrab nruab nrab ntawm lub ntiaj teb yog dab tsi?
Lub teb chaws qhov ntsuas kub yog 2.91 ° C (5.24 ° F) saum toj no 1961-1990 qhov nruab nrab, tawg cov ntaub ntawv yav dhau los tau teev tseg hauv 2013 los ntawm 0.99 ° C (1.78 ° F)
Koj pom qhov nruab nrab thiab nruab nrab hauv tableau li cas?
Kev sib txuas lus cov ntaub ntawv nrog Tableau los ntawm Ben Jones Qhov nruab nrab (lossis nruab nrab) yog txiav txim siab los ntawm kev suav tag nrho cov txiaj ntsig hauv cov ntaub ntawv teev thiab faib los ntawm tus lej ntawm qhov tseem ceeb. Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
