Qhov tseeb, qhov tseeb ntawm cov dej tsis yog tiag tiag 1 g / ml, tab sis tsawg me ntsis (ntau, tsawg tsawg), ntawm 0.9998395 g / ml ntawm 4.0 ° C(39.2° Fahrenheit). Tus nqi sib npaug ntawm 1 g / ml yog qhov koj yuav pom feem ntau, txawm li cas los xij.
Qhov twg yog qhov dej ntom ntom?
Ntawm 39 ° F (los yog 3.98 ° C kom meej)dej yog qhov ntom ntom tshaj plaws. Qhov no yog vim cov molecules nyob ze ua ke ntawm qhov kub no.
Dab tsi yog qhov ntom ntawm cov dej hauv g l?
Piv txwv li, qhov ntom ntawm cov dej ntawm 4 ° C yog 1.000 g / mLthiab ntawm 80 ° C yog 0.9718 g / mL; Qhov ceev ntawm oxygen yog 1.43 g / L ntawm 0 ° C thiab 1.10 g / L ntawm 80 ° C.
1 kg dej yog dab tsi?
Qhov ntom
Dej muaj qhov ntom 1 kg /L, yog 1 liter dej muaj qhov hnyav ntawm 1 kg.
Kuv tuaj yeem suav qhov ceev li cas?
Lub Tshuab xam zauv ceev siv tus qauv p=m/V, los yog qhov ntom (p) yog sib npaug rau pawg (m) faib los ntawm ntim (V).
