Qhov ntom yog a ntsuas ntawm huab hwm coj ib unit ntawm ntim. Qhov nruab nrab ceev ntawm ib yam khoom sib npaug nws tag nrho pawg muab faib los ntawm nws tag nrho ntim. Ib qho khoom ua los ntawm cov khoom sib piv (xws li hlau) yuav muaj qhov ntim tsawg dua li cov khoom sib npaug uas ua los ntawm qee cov khoom ntom ntom (xws li dej).

Tom qab ntawd, qhov ceev ntsuas nyob rau hauv dab tsi?

Qhov ntom yog qhov loj ntawm ib yam khoom faib los ntawm nws ntim. Qhov ntom feem ntau muaj units ntawm grams ib cubic centimeter (g / cm³). Nco ntsoov, grams yog qhov loj thiab cubic centimeters yog ib lub ntim (lub ntim tib yam li 1 milliliter).

Ib sab saum toj no, dab tsi yog qhov ceev hauv physics? Qhov ntom txhais tau tias yog qhov loj ntawm ib chav tsev ntim. Nws yog ib qho cuab yeej siv zog, uas yog lej txhais tau tias yog pawg faib los ntawm ntim: ρ = m / V. Hauv cov lus, cov ceev (ρ) ntawm ib yam khoom yog tag nrho cov huab hwm coj (m) ntawm cov khoom uas muab faib los ntawm tag nrho cov ntim (V) nyob los ntawm cov khoom.

Ntxiv rau qhov no, qhov ntim ntsuas dab tsi hauv kev tshawb fawb?

Ntim , as ntsuas nyob rau hauv chemistry, yog tus nqi ntawm qhov chaw uas muaj teeb meem occupies. Nws yog feem ntau ntsuas los ntawm liter (L), 1.057 qt. nyob rau hauv cov pa units, los yog milliliter (mL), 1/1000 ntawm ib liter, txog 0.0338 ntawm ib ooj. Nws yog feem ntau ntsuas los ntawm cylinders, flasks, pipettes, los yog syringes nyob rau hauv thiab tawm ntawm chav kuaj.

Cov kua mis ntsuas li cas?

Muaj peev xwm ua tau ntsuas nyob rau hauv ntim los yog hnyav. Volume Versus Nyhav: Raws li feem ntau cov txheej txheem them nyiaj raws li mis nyuj cov ntsiab lus khoom, nws yog qhov tsim nyog dua ntsuas luj o mis nyuj (1 litr mis nyuj Qhov nruab nrab hnyav 1.031 kg). liters x specification gravity = kilos.
