Cov hlau twg muaj qhov ntom ntawm 2.7g cm3?
Cov hlau uas tsis tshua muaj ntom ntom Hlau Lub Npe G / CC (Grams ib Cubic Centimeter) Germanium 5.32 Titanium 4.5 Txhuas 2.7
Dab tsi yog qhov ntom ntom ntom ntom ntom ntom ntom?
Ib daim phiaj density yog ib qho piv txwv ntawm kev faib cov lej sib txawv. Nws yuav siv ib ntsiav ceev kwv yees los qhia qhov tshwm sim ceev muaj nuj nqi ntawm lub nce mus nce los (saib ntxiv). Nws yog ib tug smoothed version ntawm lub histogram thiab yog siv nyob rau hauv tib lub tswvyim
Dab tsi yog vim li cas ntawm qhov ntom ntom ntom?
Ntawm cov kua-cua sib cuam tshuam, qhov nro ntawm qhov chaw tshwm sim los ntawm kev nyiam ntawm cov kua molecules ntau dua rau ib leeg (vim kev sib koom ua ke) dua li cov molecules hauv huab cua (vim adhesion)
Dab tsi yog qhov txawv ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom nrog cov piv txwv?
Nws ua haujlwm nyob rau hauv ob qho tib si loj thiab me me thiab tsis yog raws li cov pej xeem ceev. Ceev dependent yam yog cov uas tswj cov kev loj hlob ntawm ib tug pej xeem nyob rau ntawm nws lub ceev thaum ceev ywj siab yam yog cov uas tswj pejxeem kev loj hlob yam tsis muaj nyob rau nws cov ceev
Lub raj mis ntom ntom siv li cas los nrhiav qhov ntom ntawm cov kua?
Qhov loj thiab qhov loj ntawm cov molecules nyob rau hauv cov kua thiab ze npaum li cas lawv tau ntim ua ke txiav txim siab qhov ntom ntawm cov kua. Ib yam li cov khoom, qhov ntom ntawm cov kua sib npaug ntawm cov kua faib los ntawm nws qhov ntim; D = m/v. Qhov ceev ntawm cov dej yog 1 gram ib cubic centimeter
