Thaum qhov sib npaug ntawm ob cov kua sib xyaw, qhov qhov tshwj xeeb ntawm qhov sib tov yog 4. Thaum cov khoom sib npaug ntawm tib ob cov kua sib xyaw ua ke qhov tshwj xeeb lub ntiajteb txawj nqus ntawm qhov sib tov yog 3.
Thaum qhov sib npaug ntawm ob cov kua sib xyaw ua ke qhov tshwj xeeb lub ntiajteb txawj nqus?
Yog tias peb tab tom nrhiav qhov tshwj xeeb ntawm qhov sib tov nrog rau cov dej ces qhov tshwj xeeb lub ntiajteb txawj nqus yuav ib txwm sib npaug rau qhov ntom ntawm qhov sib tov. Lub ntiajteb txawj nqus tshwj xeeb yog qhov muaj tseeb. Case 1: Thaum sib npaug ntawm cov kua dej sib tov. Yog li, \[{{V}_{a}}}={{V}_{b}}], uas yuav muab sib npaug rau \[V].
Thaum sib npaug ntawm ob yam khoom sib xyaw qhov tshwj xeeb ntawm qhov sib tov yog4 thaum sib npaug qhov hnyav sib xyaw qhov tshwj xeeb gravity yog3 yog qhov tshwj xeeb ntawm ib qho ntawm cov khoom yog2 qhov tshwj xeeb ntawm qhov sib txawv?
Thaum sib npaug ntawm ob yam khoom sib xyaw, qhov tshwj xeeb ntawm cov khoom sib xyaw yog 4. Thaum sib npaug ntawm qhov hnyav ntawm tib yam khoom sib xyaw, qhov tshwj xeeb ntawm cov khoom sib xyaw yog 3. Soecufuc gravities ntawm ob yam khoom tuaj yeem ua. d1=6 thiab d2=2.
Yuav ua li cas thaum koj sib tov ob lub kua nrog tib qhov ntom?
3) Yog tias cov kua dej tsis sib haum ntawm tib qhov ntom ntom tau poob rau hauv lwm cov kua ntawm tib qhov ntom ntom thiab shaken ces cov kua resultant kua yuav muaj globules ntawm ob cov kua uas faib random ua ib qho emulsion. Nws zoo li lub thawvmuaj cov khoom ntawm ob xim sib txawv faib random.
Dab tsi yog lub ntiajteb txawj nqus thiab nws cuam tshuam li cas?
Density txhais tau tias yog huab hwm coj ib chav tsev ntim. Nws muaj SI unit kg m-3 los yog kg/m3 thiab yog qhov ntau. Lub ntiajteb txawj nqus tshwj xeeb yog qhov piv ntawm cov khoom siv qhov ntom ntom nrog cov dej ntawm 4 °C (qhov twg nws yog qhov ntom tshaj plaws thiab raug coj los ua kom muaj nqi 999.974 kg m - 3). Yog li ntawd nws yog ib qho txheeb ze uas tsis muaj units.
