Pawg yog qhov hnyav npaum li cas, ntim qhia koj tias nws loj npaum li cas, thiab ceev yog pawg faib ua ntim.
Xav txog qhov no, qhov kev sib raug zoo ntawm huab hwm coj thiab ntim hu ua dab tsi?
Qhov quotient loj hu ua density, ρ, the pawg ib chav ntim.
Puas yog qhov ntim thiab qhov ntom ntom ncaj qha lossis inversely cuam tshuam? Cov ntim nce nrog nce nyob rau hauv loj tab sis tus nqi ntawm nce ntim thaum huab hwm coj ntxiv nyob ntawm ceev . Piv txwv li: Xav txog ib lub thawv ntim dej ib nrab. Hauv qhov no, yog, ntim yog inverselyproportional rau ceev.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov kev sib raug zoo ntawm huab hwm coj thiab qhov ntom ntom thaum lub ntim ntawm txhua cov kua yog tib yam?
Cov pawg thiab qhov loj ntawm cov molecules hauv a ua kua thiab ze npaum li cas lawv tau ntim ua ke txiav txim siab ceev ntawm ua kua . Ib yam li cov khoom, cov ceev ntawm a ua kua sib npaug pawg ntawm ua kua faib los ntawm nws ntim ; D = m/v. Cov ceev dej yog 1 grams rau kub cm.
Puas yog huab hwm coj nyob ntawm qhov ntim?
Cov pawg nyob ntawm ntim thiab, inturn, lub ntim nyob ntawm ntawm pawg . Yog tias peb tswj lub siab thiab qhov kub thiab txias ntawm cov roj no thiab sau cov khoom uas tuaj yeem sib txawv ntim , zoo li lub zais pa, lossis lub tog raj kheej nrog qhov kawg ntawm qhov kawg, qhov kawg ntim nyob ntawm ncaj qha rau tus nqi ntawm cov pa uas peb txhaj.

Dab tsi yog qhov kev sib raug zoo ntawm thaj chaw saum npoo thiab ntim ntawm lub voos xwmfab?
Rau qhov cubes me dua qhov no, thaj chaw saum npoo yog ntau dua piv rau qhov ntim ntau dua li nws nyob hauv qhov loj dua (qhov ntim ntau dua piv rau thaj chaw saum npoo). qhia meej meej tias raws li qhov loj ntawm ib yam khoom nce (tsis hloov pauv), qhov piv txwv no txo qis
Dab tsi yog qhov hloov pauv kev sib raug zoo ntawm ntim thiab thaj chaw saum npoo raws li qhov khoom loj dua?
Raws li lub voos xwmfab loj zuj zus los yog lub xov tooj ntawm tes tau loj dua, ces thaj tsam ntawm qhov ntim rau qhov sib piv - SA: V piv txo. Thaum ib yam khoom / cell me me, nws muaj thaj tsam loj rau qhov ntim piv, thaum lub khoom loj / cell muaj thaj tsam me me rau qhov ntim piv
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov kev sib raug zoo ntawm kev ua lej ntawm qhov kev nyuaj siab khov kho thiab Mollality?
Kev nyuaj siab qhov chaw khov kho yog cov cuab yeej sib koom ua ke pom hauv cov kev daws teeb meem uas tshwm sim los ntawm kev qhia txog cov kuab tshuaj molecules rau cov kuab tshuaj. Cov ntsiab lus khov ntawm cov kev daws yog tag nrho qis dua li cov kuab tshuaj ntshiab thiab yog ncaj qha proportional rau molality ntawm cov kuab tshuaj
Dab tsi yog qhov kev sib raug zoo ntawm thaj chaw saum npoo thiab ntim ntawm ib lub sphere?
Rau ib tug kheej kheej, qhov chaw saum npoo yog S = 4 * Pi * R * R, qhov R yog lub vojvoog ntawm tus kheej thiab Pi yog 3.1415 Qhov ntim ntawm ib puag ncig yog V = 4 * Pi * R * R * R / 3. Yog li rau ib tug kheej kheej, qhov sib piv ntawm thaj chaw rau ntim yog muab los ntawm: S / V = 3 / R
