Clausius - Clapeyron sib npaug - ib qho piv txwv.
Xam cov mole feem ntawm cov dej (qhov hnyav).
- Xkuab tshuaj = ndej / (nqabzib + ndej).
- Molar loj ntawm cov dej yog 18 g/mol, thiab rau cov piam thaj nws yog 180.2 g/mol.
- dej = 500/18 = 27.70 mol.
- qabzib = 100/180.2 = 0.555 mol.
- Xkuab tshuaj = 27.70 / (27.70 + 0.555) = 0.98.
Ib yam li ntawd, tib neeg nug, qhov sib npaug Clausius Clapeyron sawv cev li cas?
Feem ntau cov Clausius - Clapeyron sib npaug muaj feem xyuam rau kev sib raug zoo ntawm lub siab thiab kub rau tej yam kev mob ntawm equilibrium ntawm ob theem. Ob theem yuav yog vapor thiab khoom rau sublimation los yog khoom thiab kua rau melting.
Ib tug kuj nug, C sawv cev rau dab tsi hauv Clausius Clapeyron kab zauv? (1) qhov twg ln P yog Lub ntuj logarithm ntawm vapor siab, ∆Hvap yog cua sov ntawm vaporization, R yog universal gas tas li (8.31 J·K-1mol-1), T qhov kub thiab txias, C ib qho tas mus li (tsis hais txog qhov muaj peev xwm kub).
Kuj kom paub yog, qhov sib npaug Clausius Clapeyron yog dab tsi thiab vim li cas nws tseem ceeb?
Clausius - Clapeyron sib npaug yog siv rau lub hom phiaj hauv qab no: txhawm rau kwv yees lub vapor siab ntawm qhov kub thiab txias. Txhawm rau kwv yees cov cua sov vaporization ntawm theem kev hloov pauv los ntawm cov vapor pressures ntsuas ntawm ob qhov kub.
Dab tsi yog qhov sib npaug rau cua sov ntawm vaporization?
Siv cov qauv q = m·ΔHv uas q = kub zog, m = mass, and Δ Hv = kub ntawm vaporization.

Yuav ua li cas koj xam tus qauv sib txawv ntawm PMP?
Cov mis siv nyob rau hauv PMBOK rau tus qauv sib txawv yog yooj yim. Nws tsuas yog (P-O) / 6. Qhov ntawd yog qhov pessimistic kev ua ub no kwv yees rho tawm qhov kev kwv yees qhov kev xav tau muab faib los ntawm rau. Qhov teeb meem yog qhov no nyob rau hauv tsis muaj txoj kev zoo los yog daim ntawv tsim ib qho kev ntsuas ntawm tus qauv deviation
Yuav ua li cas koj xam qhov ncig ntawm lub ntiaj teb ntawm nws latitude?
Circumference ntawm lub voj voog yog sib npaug rau 2 π r qhov twg r yog nws lub vojvoog. Nyob rau hauv lub ntiaj teb no, lub circumference ntawm tus kheej ntawm ib tug muab latitude yog 2πr(cos θ) qhov twg θ yog lub latitude thiab r yog lub vojvoog ntawm lub ntiaj teb ntawm kab zauv
Yuav ua li cas koj xam ib tug exponential equation?
Nrhiav qhov sib npaug ntawm qhov muaj nuj nqi exponential Yog tias ib qho ntawm cov ntaub ntawv cov ntsiab lus muaj daim ntawv (0,a), ces a yog tus nqi pib. Yog tias tsis muaj cov ntsiab lus ntawm cov ntaub ntawv muaj daim ntawv (0,a), hloov ob lub ntsiab lus rau hauv ob qhov sib npaug nrog daim ntawv f (x) = a (b) x displaystyle fleft(x ight) = a{left(b ight)}^ {x} f(x)=a(b)x?
Yuav ua li cas koj xam lub sij hawm nws yuav siv sij hawm mus ncig teb chaws?
Kwv yees seb koj yuav mus sai npaum li cas ntawm koj qhov kev mus ncig. Tom qab ntawd, faib koj qhov kev ncua deb ntawm koj qhov nrawm. Qhov no yuav muab rau koj anestimation ntawm koj lub sijhawm mus ncig. Piv txwv li, yog tias koj mus ncig yog 240 mais thiab koj yuav tsav 40 mais ib teev, koj lub sijhawm yuav yog 240/40 = 6hours
Yuav ua li cas koj xam lub sij hawm nws yuav siv ib yam khoom los poob?
Ntsuas qhov deb ntawm qhov khoom yuav poob hauv ko taw nrog tus pas ntsuas lossis ntsuas daim kab xev. Faib qhov kev ncua deb los ntawm 16. Piv txwv li, yog tias cov khoom yuav poob 128 ko taw, faib 128 los ntawm 16 kom tau 8. Xam cov square root ntawm cov kauj ruam 2 los nrhiav lub sij hawm nws yuav siv cov khoom poob hauv vib nas this
