A homogeneous sib tov muaj tib yam zoo li qub thiab muaj pes tsawg leeg thoob plaws. Ntau homogeneous sib tov feem ntau hu ua kev daws teeb meem. A heterogeneous sib tov muaj pom txawv tshuaj los yog theem. Cov kev daws teeb meem muaj cov khoom uas yog qhov loj ntawm atoms lossis molecules - me me dhau los pom.
Ua raws li qhov no saib, dab tsi yog homogeneous thiab heterogeneous sib tov thiab piv txwv?
A sib tov yog tsim los ntawm kev sib txuas ob lossis ntau cov khoom siv. A homogeneous sib tov zoo nkaus li niaj hnub, tsis hais qhov twg koj coj nws. Piv txwv ntawm homogeneous sib tov muaj xws li cua, saline tov, feem ntau alloys, thiab bitumen. Piv txwv ntawm heterogeneous sib tov suav nrog xuab zeb, roj thiab dej, thiab nqaij qaib noodle kua zaub.
Ib yam li ntawd, txhais li cas los ntawm homogeneous sib tov? A homogeneous sib tov yog ib yam khoom, kua, los yog gaseous sib tov uas muaj tib proportions ntawm nws cov Cheebtsam nyob rau hauv ib qho qauv muab. Hloov chaw, a heterogeneous sib tov muaj cov khoom nyob rau hauv uas proportions sib txawv thoob plaws hauv tus qauv. Ib qho piv txwv ntawm a homogeneous sib tov yog cua.
Hais txog qhov no, dab tsi zoo sib xws ntawm homogeneous thiab heterogeneous sib tov?
A homogeneous sib tov muaj ib tug uniform muaj pes tsawg leeg thiab tsos. Tus kheej cov khoom uas tsim tau a homogeneous sib tov tsis tuaj yeem pom qhov sib txawv. Ntawm qhov tod tes, a heterogeneous sib tov muaj ob lossis ntau yam khoom uas tuaj yeem pom meej, thiab txawm tias sib cais yooj yim.
Cov ntshav puas yog homogeneous lossis heterogeneous sib xyaw?
Ntshav tsis yog a homogeneous sib tov . Nws yog ib sib tov dej ( ntshav plasma) thiab khoom (liab thiab dawb ntshav cell) thiab coagulent molecules tag nrho ntab ncig hauv sib tov . Peb tuaj yeem cais tawm cov khib nyiab hauv lub centrifuge. A homogeneous sib tov yuav muaj raws nraim tib yam concentration ntawm tag nrho cov Cheebtsam nyob txhua qhov chaw.

Dab tsi yog qhov sib xws ntawm homogeneous thiab heterogeneous sib tov?
Lub homogeneous sib tov muaj ib tug uniform muaj pes tsawg leeg thiab tsos. Cov tshuaj ib leeg uas tsim ib homogeneous sib tov tsis tuaj yeem pom qhov sib txawv. Ntawm qhov tod tes, ib qho sib tov sib xyaw ua ke muaj ob lossis ntau yam khoom uas tuaj yeem pom tau meej, thiab txawm tias sib cais yooj yim
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm qhov nrawm thiab nrawm?
Kev sib piv daim duab piv rau Kev Sib Piv Ceev Ceev Tus Nqi Hloov ntawm qhov kev ncua deb Hloov pauv hloov thaum lub cev rov qab mus rau nws qhov chaw pib Yuav tsis xoom Yuav yog xoom Tsiv khoom Ceev ntawm cov khoom txav tsis tuaj yeem tsis zoo. Kev nrawm ntawm cov khoom txav tuaj yeem yog qhov zoo, tsis zoo lossis xoom
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
