Ib yam li ntawd, qhov piv txwv ntawm kev sib tov yog dab tsi? A sib tov yog ib yam khoom tsim los ntawm kev sib txuas ob lossis ntau cov khoom sib txawv hauv txoj kev uas tsis muaj tshuaj lom neeg tshwm sim. A sib tov feem ntau tuaj yeem muab cais rov qab rau hauv nws cov khoom qub. Ib txhia piv txwv ntawm sib tov yog cov zaub xam lav, dej ntsev thiab ib lub hnab sib xyaw ntawm M&M cov khoom qab zib.
Xav txog qhov no, dab tsi yog 10 piv txwv ntawm homogeneous sib tov?
Piv txwv ntawm homogeneous sib tov muaj xws li cua, saline tov, feem ntau alloys, thiab bitumen. Piv txwv ntawm heterogeneous mix suav nrog xuab zeb, roj thiab dej, thiab nqaij qaib noodle kua zaub.
Dab tsi yog 10 piv txwv ntawm cov khoom ntshiab?
Piv txwv ntawm cov khoom ntshiab muaj xws li tin, sulfur, pob zeb diamond, dej , ntshiab qab zib ( sucrose ), ntsev ( sodium chloride) thiab ci dej qab zib ( sodium bicarbonate). Crystals, feem ntau, yog cov khoom ntshiab. Tin, sulfur, thiab pob zeb diamond yog cov piv txwv ntawm cov khoom ntshiab uas yog tshuaj cov ntsiab lus.
