Lub Boltzmann kev sib npaug
Microstates yog ib lo lus siv los piav txog cov naj npawb ntawm cov kev sib txawv ntawm txoj haujlwm molecular thiab lub zog kinetic ntawm ib lub xeev thermodynamic. Cov txheej txheem uas muab ib qho nce Yog li ntawd, nyob rau hauv tus naj npawb ntawm microstates nce tus entropy.
Tib neeg kuj nug, qhov twg cov tshuaj tiv thaiv ua rau nce hauv entropy?
(5) Txhua yam tshuaj tshuaj tiv thaiv uas nce tus naj npawb ntawm cov roj molecules kuj nce entropy . Ib qho tshuaj tshuaj tiv thaiv uas nce tus naj npawb ntawm cov roj molecules yuav yog a tshuaj tiv thaiv uas nchuav lub zog rau hauv ib qho system. Ntau lub zog ua rau koj ntau dua entropy thiab randomness ntawm cov atoms.
Qhov thib ob, koj paub li cas yog tias entropy nce lossis txo qis? A txo nyob rau hauv tus naj npawb ntawm moles ntawm cov khoom sab txhais tau tias qis dua entropy . Ib nce nyob rau hauv tus naj npawb ntawm moles ntawm cov khoom sab txhais tau tias ntau dua entropy . Yog cov tshuaj tiv thaiv muaj ntau theem, ntau lawm cov pa roj nce tus entropy ntau tshaj ib qho nce nyob rau hauv moles ntawm cov kua los yog khoom.
Tsis tas li ntawd, koj yuav xam qhov nce entropy li cas?
Entropy nce thaum koj mus los ntawm cov khoom mus rau cov kua rau roj, thiab koj tuaj yeem twv seb puas yog entropy kev hloov pauv yog qhov zoo lossis tsis zoo los ntawm kev saib cov theem ntawm cov reactants thiab cov khoom. Thaum twg muaj ib qho nce hauv gas moles, entropy yuav nce.
Puas yog entropy zoo lossis tsis zoo?
Cov tshuaj tiv thaiv yuav tshwm sim, raws li nyob rau hauv cov tshuaj tiv thaiv exothermic H yog tsis zoo , thiab if entropy nce, ces S yog zoo , yog: Total entropy hloov yog zoo , yog li cov tshuaj tiv thaiv ua tau. Cov tshuaj tiv thaiv tsis tuaj yeem tshwm sim, raws li H yog zoo thiab S yog tsis zoo : Tag nrho entropy hloov yog tsis zoo thiab yog li cov tshuaj tiv thaiv tsis tuaj yeem tshwm sim.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Cov coefficients hauv kev sib npaug tshuaj sib npaug qhia koj li cas txog cov reactants thiab cov khoom?
Cov coefficients ntawm kev sib npaug chemicalequation qhia peb cov txheeb ze ntawm moles ntawm reactants thiab cov khoom. Hauv kev daws teeb meem stoichiometric, kev hloov pauv ntawm moles ntawm reactants rau moles ntawm cov khoom raug siv. Hauv kev suav loj, cov molar loj yog xav tau los hloov cov huab hwm coj mus rau moles
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
