- Cov lus ntsev yog hu ua sodium chloride. …
- Ib homogeneous sib tov yog ib qho sib xyaw uas cov muaj pes tsawg leeg sib xws thoob plaws qhov sib xyaw. …
- Ib qho sib xyaw ua ke yog qhov sib xyaw uas muaj qhov sib xyaw tsis sib xws thoob plaws qhov sib xyaw.
Koj paub qhov txawv ntawm homogeneous thiab heterogeneous li cas?
Ib homogenous sib tov yog qhov sib xyaw uas cov khoom sib xyawnrog rau ib leeg thiab nws cov muaj pes tsawg leeg yog uniform thoob plaws hauv cov tshuaj. Ib qho kev sib xyaw heterogenous yog qhov sib xyaw uas cov muaj pes tsawg leeg tsis sib xws thoob plaws thiab cov khoom sib txawv tau pom.
Dab tsi yog qhov txawv ntawm homogeneous thiab heterogeneous sib tov muab piv txwv?
Ib qho kev daws teeb meem zoo ib yam, txawm tias koj coj nws li cas. Homogeneous sib tov yog qhov chaw ntawm dej, ntsev tov, qee cov alloys, thiab bitumen. xuab zeb, roj thiab dej, thiab nqaij qaib noodle soup yog piv txwv ntawm kev sib xyaw ua ke.
Dab tsi yog homogeneous sib tov?
Ib homogeneous sib tov yog ib qho sib xyaw uas muaj pes tsawg leeg sib xyaw thoob plaws qhov sib tovCov dej ntsev uas tau piav saum toj no yog homogeneous vim cov ntsev yaj tau sib npaug sib npaug thoob plaws hauv cov qauv dej ntsev.. … Ib tug yam ntxwv ntawm kev sib tov yog tias lawv tuaj yeem muab cais ua lawv cov khoom.
YPuas mis yog homogeneous sib tov?
Homogeneous mixs tseem hu ua kev daws. … Mis, piv txwv li, zoo nkaus li homogeneous, tab sis thaum kuaj xyuas hauv lub tshuab ntsuas, nws pom meej meej muaj cov pob me me ntawm cov roj thiab cov protein uas tau tawg hauv dej. Lub Cheebtsam ntawm heterogeneous mixs feem ntau yog sib cais los ntawm txoj kev yooj yim.
