Specific Gravity ntawm Hlau Hlau

Lub ntiajteb txawj nqus tshwj xeeb, tseem hu ua txheeb ze ntom ntom, hais txog qhov sib piv ntawm qhov ntom ntawm cov khoom rau qhov ntom ntawm cov khoom siv raws li cov xwm txheej. Rau cov hlau hlau, nws lub ntiajteb txawj nqus tshwj xeeb feem ntau qhia txog qhov ntom ntawm cov dej. Raws li cov txheej txheem, lub ntiajteb txawj nqus ntawm cov hlau zoo tib yam yog kwv yees li 7.85. Qhov no txhais tau hais tias qhov loj ntawm tib lub ntim ntawm cov hlau hlau yog 7.85 npaug ntawm cov dej. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus nqi no yog raws li tus qauv ceev ntawm cov hlau thiab tej zaum yuav txawv ntawm daim ntawv thov tiag tiag vim yog yam xws li cov alloy tshwj xeeb, txheej txheem tsim khoom, thiab kub ntawm cov hlau hlau.
