Cov khoom siv yog lub cev, tshuaj, lossis cov khoom siv kho tshuab ntawm cov khoom tshwj xeeb uas yuav txiav txim siab nws txoj haujlwm thiab kev tsim khoom.
8 lub cev yog dab tsi?
Lub cev lub cev muaj xws li: zoo li, kev ntxhib los mos, xim, tsw, melting point, boiling point, ntom, solubility, polarity, thiab ntau lwm yam.
Cov khoom yog dab tsi?
Cov khoom siv yog qhov loj, zoo li, qhov ntom ntawm cov khoom, thiab lawv cov khoom siv kho qhov muag (Young's modulus, yield stress, fracture toughness, etc.
Dab tsi yog piv txwv ntawm lub cev muaj zog?
piv txwv: mass, ntom, xim, boiling point, kub, thiab ntim. tsis yog piv txwv- txhua yam uas tsis yog khoom ntiag tug yuav yog qhov tsis piv txwv. Kev xav tsis yog lub cev khoom.
