Txhais ntawm khov . 1: muaj tuab los yog nplaum sib xws : viscid khov zais cia khov pob kws syrup. 2 technical: muaj los yog tus yam ntxwv los ntawm ib tug siab tsis kam mus ntws khov lava.
Hais txog qhov no, qhov txawv ntawm qhov sib xws thiab viscosity yog dab tsi?
Raws li lub npe qhov sib txawv ntawm viscosity thiab sib xws yog li viscosity yog (uncountable) lub xeev ntawm ua khov thaum sib xws yog lub zos coherence.
Qhov thib ob, nws txhais li cas thaum ib yam dab tsi khov? Viscous txhais tau tias nplaum, nplaum thiab syrup. Yog li yog ib yam dab tsi khov , feem ntau koj tsis xav lo koj cov ntiv tes rau hauv nws - uas mus rau boogers thiab maple phoov zoo ib yam. Tsis yog ib qho khoom thiab tsis yog kua, cov kws tshawb fawb nyiam hais tias khov yam tsis ntws yooj yim heev.
Tsis tas li ntawd, puas viscosity txhais tau tias thickness?
Nws yog feem ntau pom tau tias " tuab ", los yog tiv thaiv pouring. viscosity piav qhia txog cov kua dej sab hauv tsis kam ntws thiab tej zaum yuav xav tias yog ib qho kev ntsuas ntawm cov kua dej sib txhuam. Yog li, dej yog "thin", muaj qis viscosity , thaum zaub roj yog " tuab "muaj siab viscosity.
Dab tsi yog ob yam khoom uas muaj qhov sib xws?
Cov kua uas nws cov molecules yog polar lossis tuaj yeem tsim hydrogen bonds feem ntau yog ntau dua khov tshaj qhov zoo sib xws nonpolar tshuaj . Zib ntab, feem ntau yog qabzib thiab fructose (saib daim duab hauv qab no) yog ib qho piv txwv zoo ntawm cov kua uas tshuav nws. viscosity rau hydrogen bonding. Cov kua uas muaj cov molecules ntev yog invariably heev khov.

Qhov sib txawv ntawm kev ntsuas thiab cov ntsiab lus tsis sib xws yog dab tsi?
Qhov sib txawv tseem ceeb ntawm cov ntsiab lus tsis sib xws thiab kev ntsuas yog tias cov ntsiab lus tsis sib xws yog qhov kev xeem uas cov chaw ntsuas ntsuas tau ua tiav ib tus zuj zus qhov kev ntsuas yog kev ntsuas uas ntau chav nyob tau ua tiav ib txhij. Tsis tas li ntawd, cov txheej txheem kev soj ntsuam ntawm cov ntsiab lus kev ntsuas qhov sib xws yog tib yam rau txhua chav
Lub teb chaws zoo sib xws txoj kev xav yog dab tsi?
Lub teb chaws Similarity Theory. Lub tswv yim hais tias lub teb chaws uas zoo sib xws yog feem ntau yuav ua lag luam nrog ib leeg. Cov kev zoo no yuav suav nrog theem kev txhim kho, kev txuag nyiaj, thiab cov peev txheej ntuj, thiab lwm yam
Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm Kev Txom Nyem Loj thiab Kev Nyuaj Siab Loj?
Kev nyuaj siab yog ib qho kev lag luam poob qis qhov twg GDP tiag tiag poob ntau dua 10 feem pua. Kev lag luam kev lag luam yog kev lag luam poob qis uas tsis tshua muaj hnyav. Los ntawm qhov yardstick no, kev nyuaj siab kawg hauv Tebchaws Meskas yog txij lub Tsib Hlis 1937 txog rau Lub Rau Hli 1938, qhov twg GDP tiag tiag poob los ntawm 18.2 feem pua
Dab tsi yog qhov sib txawv ntawm cov ntsiab lus sib xws thiab kev ntsuam xyuas?
Qhov sib txawv tseem ceeb ntawm cov ntsiab lus tsis sib xws thiab kev ntsuam xyuas yog tias cov ntsiab lus tsis sib xws yog qhov kev ntsuam xyuas uas cov ntsuas ntsuas tau ua tiav ib tus zuj zus thaum qhov kev ntsuam xyuas yog qhov kev sim uas ntau chav ua tiav ib txhij. Tsis tas li ntawd, cov txheej txheem kev soj ntsuam ntawm cov ntsiab lus kev ntsuas qhov sib xws yog tib yam rau txhua chav
